By default Phoenix deploys with authentication disabled as you may be just trying Phoenix for the very first time or have Phoenix deployed in a VPC. However you might want to further protect access to your data via authentication. Below are the steps.
Authentication will stop collecting traces and block all API access until API keys are created. For that reason we recommend scheduling some downtime if you have already deployed phoenix.

​
Setup

To enable authentication on your Phoenix, you will have to set two environment variables:
VariableDescriptionExample Value
PHOENIX_ENABLE_AUTHSet to True to enable authentication on your platformTrue or False
PHOENIX_SECRETA long string value that is used to sign JWTs for your deployment. It should be a good mix of characters and numbers and should be kept in a secret store of some kind.3413f9a7735bb780c6b8e4db7d946a492b64d26112a955cdea6a797f4c833593
The following environment variables are optional but recommended:
VariableDescription
PHOENIX_USE_SECURE_COOKIESIf set to True, access and refresh tokens will be stored in secure cookies. Defaults to False.
PHOENIX_CSRF_TRUSTED_ORIGINSA comma-separated list of origins allowed to bypass Cross-Site Request Forgery (CSRF) protection. This setting is recommended when configuring OAuth2 clients or sending password reset emails. If this variable is left unspecified or contains no origins, CSRF protection will not be enabled. In such cases, when a request includes origin or referer headers, those values will not be validated.
Deploy Phoenix with the above environment variables set. You will know that you have setup authentication correctly if the UI navigates to to a login screen. By default Phoenix will create an admin user account. To get started:
  1. Log in as the admin user. The email should be admin@localhost and the password will be admin
  2. Set a new password for admin. You will be prompted to set a new password. Use a sufficiently complex password and save it in a safe place.
  3. Go to the settings page on the left nav and create your first system API key. This API key can be used to log traces, use the Phoenix client, and programmatically hit Phoenix’s APIs. Store the system API key in a safe place.
  4. In your application code, make sure to set the proper authentication headers with the system API key. Phoenix respects headers in the form of bearer auth, meaning that you should set the header in the form Authorization: Bearer <token>. Note that if you are using the Phoenix Client or Phoenix Otel, you simply need to set the PHOENIX_API_KEY environment variable.
Re-deploy your application with the API key created above and you will see traces stream in as before.
Initial admin password: You can set the initial password via the PHOENIX_DEFAULT_ADMIN_INITIAL_PASSWORD environment variable. It is only read on first startup when the default admin account is created; subsequent changes have no effect if the account already exists. If you need to change the admin password later, do so from the UI or via an admin password reset.Docker example:
docker run \
  -e PHOENIX_ENABLE_AUTH=true \
  -e PHOENIX_SECRET=change-me-32chars-min1digit1lower \
  -e PHOENIX_DEFAULT_ADMIN_INITIAL_PASSWORD='strong-admin-password' \
  -p 6006:6006 arizephoenix/phoenix:latest
Helm users can set auth.defaultAdminPassword or provide the secret key PHOENIX_DEFAULT_ADMIN_INITIAL_PASSWORD in the chart’s Secret.

​
User Management

Users can be added and removed from a Phoenix instance with authentication enabled. Users have one of three roles: admin, member, or viewer. See permissions below to learn more about the permissions for each role. Only admins can manage phoenix users. They can add, delete, and reset the passwords of other users. To manage users go to the /settings page.

​
Permissions

This section outlines the specific actions that users can perform based on their assigned roles within the system: Admin, Member, and Viewer. The permission matrix is divided into two main categories:
  • Mutations: Operations that allow users to create, update, or delete data within the system.
  • Queries: Operations that enable users to retrieve or view data from the system.

​
Mutations

Mutations are operations that enable users to create, update, or delete data within the system. This permission matrix ensures that only authorized roles can execute sensitive actions, such as managing users and API keys, while allowing members to perform essential account-related updates like changing their own passwords and usernames. Viewers have read-only access and cannot perform mutations.
Neither an Admin, Member, nor Viewer is permitted to change email addresses.
ActionAdminMemberViewer
Create User✅ YesNoNo
Delete User✅ YesNoNo
Change Own Password✅ Yes✅ Yes✅ Yes

​
Queries

Queries are operations that allow users to retrieve and view data from the system.
This table only shows actions that a Member or Viewer is not permitted to do. Actions without restrictions (such as viewing traces, projects, datasets, etc.) are omitted.
ActionAdminMemberViewer
List All System API Keys✅ YesNoNo
List All User API Keys✅ YesNoNo

Fetch Other User’s Info, e.g. emails✅ YesNoNo

​
REST API Permissions (v1/ endpoints)

For programmatic access via REST API endpoints (paths beginning with /v1/), permissions are determined by both the user’s role and the HTTP method used:
Endpoint CategoryAdminMemberViewer
GET requests (read operations)
Projects, datasets, experiments, prompts, spans, traces, annotations, annotation configs, evaluations		✅ Yes✅ Yes✅ Yes
POST/PUT/DELETE requests (write operations)
Creating, updating, or deleting resources		✅ Yes✅ Yes❌ No
(403 Forbidden)
User management endpoints
GET /v1/users
POST /v1/users
DELETE /v1/users/		✅ Yes❌ No
(403 Forbidden)		❌ No
(403 Forbidden)
Project management endpoints
PUT /v1/projects/
DELETE /v1/projects/		✅ Yes❌ No
(403 Forbidden)		❌ No
(403 Forbidden)
Viewer role restrictions for REST API:
  • Viewers have read-only access to v1/ endpoints
  • All GET requests are allowed (viewing projects, datasets, experiments, traces, spans, etc.)
  • All write operations (POST, PUT, DELETE) return 403 Forbidden
  • User management and project CRUD operations are also blocked
Examples of blocked operations for Viewers:
  • Creating datasets: POST /v1/datasets/upload
  • Creating experiments: POST /v1/datasets/{id}/experiments
  • Creating annotations: POST /v1/span_annotations
  • Uploading traces: POST /v1/traces
  • Deleting resources: DELETE /v1/datasets/{id}, DELETE /v1/experiments/{id}

​
API Keys

There are two kinds of API keys in Phoenix: system and user.

​
System Keys

System keys act on behalf of the system as a whole rather than any particular user. They can only be created by admins, are not meaningfully associated with the admin who creates them except for auditing purposes, and do not disappear if that admin is deleted. A system key would be the recommended kind of key to use in programmatic interactions with Phoenix that do not involve a user (e.g., automated flows querying our REST APIs).

​
User Keys

User API keys are associated with and act on behalf of the user to which they are issued. That user has the ability to view and delete their own user keys, and if the user is deleted, so are all of their associated user keys. A user might create their own user key into order to run an experiment in a notebook, for example.

​
Setting and Using API Keys with Environment Variables

Phoenix API keys can be set with the PHOENIX_API_KEY environment variable: 
export PHOENIX_API_KEY=<SYSTEM-OR-USER-KEY>
If authentication is enabled on Phoenix, all interactions with the server need to include an authorization header. Phoenix will read the PHOENIX_API_KEY environment variable, and automatically include it as an authorization header. Interactions with Phoenix include:
  • Using phoenix.Client
  • Running experiments
  • Sending OpenInference traces (more details below)

​
Sending OpenInference traces

API Keys also need to be included on OpenInference traces sent to the Phoenix server. If you’ve set the PHOENIX_API_KEY environment variable, the phoenix.otel module will automatically include an authorization header with the API key: 
from phoenix.otel import register

tracer_provider = register()
Alternatively, you can explicitly set the authorization header on the exporter if using OpenTelemetry primitives directly. 
from opentelemetry.exporter.otlp.proto.http.trace_exporter import OTLPSpanExporter
from opentelemetry.sdk import trace as trace_sdk
from opentelemetry.sdk.trace.export import ConsoleSpanExporter, SimpleSpanProcessor

endpoint = "http://127.0.0.1:6006/v1/traces"
tracer_provider = trace_sdk.TracerProvider()
exporter = OTLPSpanExporter(
    endpoint,
    headers={"authorization": "Bearer <SYSTEM-OR-USER-KEY>"},
)
tracer_provider.add_span_processor(SimpleSpanProcessor(exporter))
If setting authorization headers explicitly, ensure that the header field is lowercased to ensure compatibility with sending traces via gRPC

​
Password Recovery

The password recovery methods described in this section apply when recovering a locally authenticated user’s password. In order recover a password for a user logged in via a third-party identity provider such as Google, you will have to consult the documentation of these identity providers

​
With SMTP (Simple Mail Transfer Protocol)

Using SMTP ensures that your password recovery emails are delivered reliably and securely. SMTP is the standard protocol for sending emails, making sure that you receive the reset link promptly in your inbox. Below is an example configuration to enable SMTP for sendgrid. 
export PHOENIX_SMTP_HOSTNAME=smtp.sendgrid.net
export PHOENIX_SMTP_USERNAME=apikey
export PHOENIX_SMTP_PASSWORD=XXXXXXXXXXXXXXXXX

​
Without SMTP

If SMTP is not configured, you have a few options to recover your forgotten password:
  • Contact an administrator and request that they reset your password. Admins can reset user passwords on the settings page.
  • As a last resort, you can manually update the database tuple that contains your password salt and hash.

​
Configuring OAuth2 Identity Providers

Phoenix supports login via third-party identity providers (IDPs), including:
OAuth2 enables applications such as Phoenix to authorize access to resources via identity providers (IDPs) rather than storing and verifying user credentials locally. OpenID Connect is an extension of OAuth2 that additionally authenticates users by verifying identity and providing Phoenix with user information such as email address, username, etc. Phoenix integrates with OpenID Connect IDPs that have a “well-known configuration endpoint” at GET /.well-known/openid-configuration, which provides a standardized way to discover information about the IDP’s endpoints and capabilities.
Phoenix uses the OAuth2 authorization code flow for web applications, which requires setting a few environment variables in addition to PHOENIX_ENABLE_AUTH and PHOENIX_SECRET:
Environment VariableDescription
PHOENIX_OAUTH2_<IDP>_CLIENT_IDThe client ID generated by the IDP when registering the application. (Required)
PHOENIX_OAUTH2_<IDP>_CLIENT_SECRETThe client secret generated by the IDP when registering the application. Required by default for confidential clients. Only optional when TOKEN_ENDPOINT_AUTH_METHOD is explicitly set to none (for public clients without client authentication).
PHOENIX_OAUTH2_<IDP>_OIDC_CONFIG_URLThe URL to the OpenID Connect well-known configuration endpoint. Entering this URL in your browser will return a JSON object containing authorization server metadata. Must be HTTPS except for localhost. (Required)

​
Optional OAuth2 Configuration

The following optional environment variables provide additional control over OAuth2 authentication behavior:
Environment VariableDescription
PHOENIX_OAUTH2_<IDP>_DISPLAY_NAMEA user-friendly name for the identity provider shown in the UI. If not set, Phoenix will generate a display name based on the IDP identifier.
PHOENIX_OAUTH2_<IDP>_ALLOW_SIGN_UPWhether to allow new user registration via this OAuth2 provider. Defaults to True. When set to False, only existing users can sign in. The system will check if the user exists in the database by their email address. If the user does not exist or has a password set (local auth), they will be redirected to the login page with an error message.
PHOENIX_OAUTH2_<IDP>_AUTO_LOGINAutomatically redirect to this provider’s login page, skipping the Phoenix login screen. Defaults to False. Useful for single sign-on deployments. Note: Only one provider should have AUTO_LOGIN enabled if you configure multiple IDPs.
PHOENIX_OAUTH2_<IDP>_USE_PKCEEnable PKCE (Proof Key for Code Exchange) with S256 code challenge method for enhanced security. PKCE protects the authorization code from interception and can be used with both public clients and confidential clients. This setting is orthogonal to client authentication—whether CLIENT_SECRET is required is determined solely by TOKEN_ENDPOINT_AUTH_METHOD, not by USE_PKCE. Defaults to False.
PHOENIX_OAUTH2_<IDP>_TOKEN_ENDPOINT_AUTH_METHODOAuth2 token endpoint authentication method. This setting determines how the client authenticates with the token endpoint and whether CLIENT_SECRET is required. If not set, defaults to requiring CLIENT_SECRET (confidential client). Options:
• client_secret_basic: Send credentials in HTTP Basic Auth header (most common). CLIENT_SECRET is required. This is the assumed default behavior if not set.
• client_secret_post: Send credentials in POST body (required by some providers). CLIENT_SECRET is required.
• none: No client authentication (for public clients). CLIENT_SECRET is not required. Use this for public clients that cannot securely store a client secret, typically in combination with PKCE.

Most providers work with the default behavior. Set this explicitly only if your provider requires a specific method or if you’re configuring a public client.
PHOENIX_OAUTH2_<IDP>_SCOPESAdditional OAuth2 scopes to request (space-separated). These are added to the required baseline scopes openid email profile. For example, set to offline_access groups to request refresh tokens and group information. The baseline scopes are always included and cannot be removed.
PHOENIX_OAUTH2_<IDP>_GROUPS_ATTRIBUTE_PATHJMESPath expression to extract group/role claims from the OIDC ID token or userinfo endpoint response. The path navigates nested JSON structures to find group/role information. This claim is checked from both the ID token and userinfo endpoint (if available). The result is normalized to a list of strings for group matching. See jmespath.org for full syntax.

⚠️ IMPORTANT: Claim keys with special characters (colons, dots, slashes, hyphens, etc.) MUST be enclosed in double quotes.

Common JMESPath patterns:
• Simple keys: groups - extracts top-level array
• Nested keys: resource_access.phoenix.roles - dot notation for nested objects
• Array projection: teams[*].name - extracts ‘name’ field from each object in array
• Array indexing: groups[0] - gets first element

Common provider examples:
• Google Workspace: groups
• Azure AD/Entra ID: roles or groups
• Keycloak: resource_access.phoenix.roles (nested structure)
• AWS Cognito: "cognito:groups" (use quotes for colon)
• Okta: groups
• Auth0 (custom namespace): "https://myapp.com/groups" (use quotes for special chars)
• Custom objects: teams[*].name (extract field from array of objects)

If not set, group-based access control is disabled for this provider.
PHOENIX_OAUTH2_<IDP>_ALLOWED_GROUPSComma-separated list of group names that are permitted to sign in. Users must belong to at least one of these groups (extracted via GROUPS_ATTRIBUTE_PATH) to authenticate successfully. Works together with GROUPS_ATTRIBUTE_PATH to implement group-based access control. If not set, all authenticated users can sign in (subject to ALLOW_SIGN_UP restrictions).

Example: PHOENIX_OAUTH2_OKTA_ALLOWED_GROUPS="admin,developers,viewers"

Note: Both GROUPS_ATTRIBUTE_PATH and ALLOWED_GROUPS must be configured together. If one is set, the other is required.
PHOENIX_OAUTH2_<IDP>_ROLE_ATTRIBUTE_PATHJMESPath expression to extract user role claim from the OIDC ID token or userinfo endpoint response. Similar to GROUPS_ATTRIBUTE_PATH but for extracting a single role value. See jmespath.org for full syntax.

⚠️ IMPORTANT: Claim keys with special characters MUST be enclosed in double quotes.
Examples: "https://myapp.com/role", "custom:role", user.profile."app-role"

Common patterns:
• Simple key: role - extracts top-level string
• Nested key: user.organization.role - dot notation for nested objects
• Array element: roles[0] - gets first role from array
• Constant value: 'MEMBER' - assigns a fixed role to all users from this IDP (no mapping needed)
• Conditional logic: contains(groups[*], 'admin') && 'ADMIN' || 'VIEWER' - compute role from group membership using logical operators (returns Phoenix role directly, no mapping needed)

This claim is used with ROLE_MAPPING to automatically assign Phoenix roles (ADMIN, MEMBER, VIEWER) based on the user’s role in your identity provider. The extracted role value is matched against keys in ROLE_MAPPING to determine the Phoenix role.

Advanced: If the JMESPath expression returns a valid Phoenix role name (ADMIN, MEMBER, VIEWER) directly, ROLE_MAPPING is optional - the value will be used as-is after case-insensitive validation.

⚠️ Role Update Behavior:
• When ROLE_ATTRIBUTE_PATH IS configured: User roles are synchronized from the IDP on EVERY login. This ensures Phoenix roles stay in sync with your IDP’s role assignments.
• When ROLE_ATTRIBUTE_PATH is NOT configured: User roles are preserved as-is (backward compatibility). New users get VIEWER role (least privilege), existing users keep their current roles.
PHOENIX_OAUTH2_<IDP>_ROLE_MAPPINGMaps identity provider role values to Phoenix roles. Format: IdpRole1:PhoenixRole1,IdpRole2:PhoenixRole2

Phoenix roles (case-insensitive):
• ADMIN: Full system access, can manage users and settings
• MEMBER: Standard user access, can create and manage own resources
• VIEWER: Read-only access, cannot create or modify resources

Example mappings:
•PHOENIX_OAUTH2_OKTA_ROLE_MAPPING="Owner:ADMIN,Developer:MEMBER,Guest:VIEWER"
•PHOENIX_OAUTH2_KEYCLOAK_ROLE_MAPPING="admin:ADMIN,user:MEMBER"

⚠️ Security: The SYSTEM role cannot be assigned via OAuth2. Attempts to map to SYSTEM will be rejected.

Optional Behavior (no mapping required):
If ROLE_MAPPING is not configured but ROLE_ATTRIBUTE_PATH is set, the system will use the IDP role value directly if it exactly matches “ADMIN”, “MEMBER”, or “VIEWER” (case-insensitive). This allows IDPs that already use Phoenix’s role names to work without explicit mapping.

IDP role keys are case-sensitive and must match exactly. Phoenix role values are case-insensitive but will be normalized to uppercase (ADMIN, MEMBER, VIEWER). If a user’s IDP role is not in the mapping, behavior depends on ROLE_ATTRIBUTE_STRICT:
• strict=false (default): User gets VIEWER role (least privilege)
• strict=true: User is denied access

Works together with ROLE_ATTRIBUTE_PATH. If ROLE_ATTRIBUTE_PATH is set but ROLE_MAPPING is not, the IDP role value is used directly if it matches a valid Phoenix role (ADMIN, MEMBER, VIEWER). If the IDP role doesn’t match a valid Phoenix role, behavior depends on ROLE_ATTRIBUTE_STRICT.
PHOENIX_OAUTH2_<IDP>_ROLE_ATTRIBUTE_STRICTControls behavior when role cannot be determined from identity provider claims. Defaults to false.

When true:
• Missing role claim → access denied
• Role not in ROLE_MAPPING → access denied
• Empty/invalid role value → access denied

When false (default):
• Missing/unmapped/invalid role → user gets VIEWER role (least privilege, fail-safe)

Strict mode is recommended for high-security environments where all users must have explicitly assigned roles. Non-strict mode (default) is more forgiving and suitable for gradual rollout of role mapping.

Example: PHOENIX_OAUTH2_OKTA_ROLE_ATTRIBUTE_STRICT=true

Note: This setting only applies when ROLE_ATTRIBUTE_PATH is configured. If ROLE_ATTRIBUTE_PATH is not set, this setting is ignored.
Group-based access control requirements:
  • If you set ALLOWED_GROUPS, you must also set GROUPS_ATTRIBUTE_PATH to extract groups from the ID token.
  • If you set GROUPS_ATTRIBUTE_PATH, you must also set ALLOWED_GROUPS to specify which groups are allowed.
  • Group-based access control is evaluated per-provider: if a user authenticates via an IDP with ALLOWED_GROUPS configured, they must belong to one of those groups to sign in.
Role mapping configuration:
  • ROLE_ATTRIBUTE_PATH and ROLE_MAPPING work together to automatically assign Phoenix roles based on IDP roles.
  • If ROLE_ATTRIBUTE_PATH is configured, user roles are synchronized from the IDP on every login.
  • If ROLE_ATTRIBUTE_PATH is not configured, new OAuth2 users get the VIEWER role by default and existing users keep their current roles.
  • Groups control access (who can sign in), while roles control permissions (what users can do).

​
Multiple Identity Providers

You can configure multiple IDPs simultaneously by setting environment variables for each provider with different IDP identifiers. Users will see all configured providers as login options on the Phoenix login page. Each IDP is configured independently with its own set of variables. Example with both Google and Okta: 
# Google OAuth
export PHOENIX_OAUTH2_GOOGLE_CLIENT_ID=google_client_id
export PHOENIX_OAUTH2_GOOGLE_CLIENT_SECRET=google_secret
export PHOENIX_OAUTH2_GOOGLE_OIDC_CONFIG_URL=https://accounts.google.com/.well-known/openid-configuration

# Internal Okta with group restrictions
export PHOENIX_OAUTH2_OKTA_CLIENT_ID=okta_client_id
export PHOENIX_OAUTH2_OKTA_CLIENT_SECRET=okta_secret
export PHOENIX_OAUTH2_OKTA_OIDC_CONFIG_URL=https://your-domain.okta.com/.well-known/openid-configuration
export PHOENIX_OAUTH2_OKTA_GROUPS_ATTRIBUTE_PATH=groups
export PHOENIX_OAUTH2_OKTA_ALLOWED_GROUPS="engineering,platform-team"

​
Common OAuth2 Configuration Examples

Public client with PKCE (no client secret):
PKCE support requires Phoenix 12.4.0 or later.
export PHOENIX_OAUTH2_MOBILE_CLIENT_ID=mobile_app_id
export PHOENIX_OAUTH2_MOBILE_OIDC_CONFIG_URL=https://auth.example.com/.well-known/openid-configuration
export PHOENIX_OAUTH2_MOBILE_TOKEN_ENDPOINT_AUTH_METHOD=none
export PHOENIX_OAUTH2_MOBILE_USE_PKCE=true
With nested group path (Keycloak): 
export PHOENIX_OAUTH2_KEYCLOAK_GROUPS_ATTRIBUTE_PATH=resource_access.phoenix.roles
export PHOENIX_OAUTH2_KEYCLOAK_ALLOWED_GROUPS="admin,developer"
With special characters in path (AWS Cognito - quotes REQUIRED): 
export PHOENIX_OAUTH2_COGNITO_GROUPS_ATTRIBUTE_PATH='"cognito:groups"'
export PHOENIX_OAUTH2_COGNITO_ALLOWED_GROUPS="Administrators,PowerUsers"
With namespaced claims (Auth0 - quotes REQUIRED): 
export PHOENIX_OAUTH2_AUTH0_GROUPS_ATTRIBUTE_PATH='"https://myapp.com/groups"'
export PHOENIX_OAUTH2_AUTH0_ALLOWED_GROUPS="admin,users"
With array projection (extract names from objects): 
export PHOENIX_OAUTH2_CUSTOM_GROUPS_ATTRIBUTE_PATH="teams[*].name"
export PHOENIX_OAUTH2_CUSTOM_ALLOWED_GROUPS="engineering,operations"
Single sign-on with auto-login: 
export PHOENIX_OAUTH2_COMPANY_DISPLAY_NAME="Company SSO"
export PHOENIX_OAUTH2_COMPANY_AUTO_LOGIN=true
export PHOENIX_OAUTH2_COMPANY_ALLOW_SIGN_UP=false
With role mapping (simple): 
export PHOENIX_OAUTH2_OKTA_ROLE_ATTRIBUTE_PATH=role
export PHOENIX_OAUTH2_OKTA_ROLE_MAPPING="Owner:ADMIN,Developer:MEMBER,Viewer:VIEWER"
With role mapping (nested path for Keycloak): 
export PHOENIX_OAUTH2_KEYCLOAK_ROLE_ATTRIBUTE_PATH=resource_access.phoenix.role
export PHOENIX_OAUTH2_KEYCLOAK_ROLE_MAPPING="admin:ADMIN,user:MEMBER"
With role mapping in strict mode (deny unmapped roles): 
export PHOENIX_OAUTH2_OKTA_ROLE_ATTRIBUTE_PATH=role
export PHOENIX_OAUTH2_OKTA_ROLE_MAPPING="Owner:ADMIN,Developer:MEMBER"
export PHOENIX_OAUTH2_OKTA_ROLE_ATTRIBUTE_STRICT=true
With conditional logic to compute role from groups (no mapping needed): 
export PHOENIX_OAUTH2_OKTA_ROLE_ATTRIBUTE_PATH="contains(groups[*], 'admin') && 'ADMIN' || contains(groups[*], 'editor') && 'MEMBER' || 'VIEWER'"
With both groups and roles (groups control access, roles control permissions): 
export PHOENIX_OAUTH2_OKTA_GROUPS_ATTRIBUTE_PATH=groups
export PHOENIX_OAUTH2_OKTA_ALLOWED_GROUPS="engineering,platform-team"
export PHOENIX_OAUTH2_OKTA_ROLE_ATTRIBUTE_PATH=role
export PHOENIX_OAUTH2_OKTA_ROLE_MAPPING="Owner:ADMIN,Developer:MEMBER,Guest:VIEWER"
Default role behavior:
  • If ROLE_ATTRIBUTE_PATH is not configured: New OAuth2 users are initially added as VIEWER (least privilege). Their role can be changed after their first login by a Phoenix admin. Existing users keep their current roles.
  • If ROLE_ATTRIBUTE_PATH is configured: User roles are automatically synchronized from the IDP on every login based on the role mapping configuration.

  1. Register a Phoenix client application with your IDP. If prompted to select an application type, select traditional web application or a similarly named application type that allows you to generate a client secret in addition to a client ID.
  2. Find the well-known configuration endpoint for your IDP.
  3. Deploy Phoenix with the environment variables described above, substituting <IDP> with your IDP name, e.g., AUTH0. If you have configured a root path via the PHOENIX_HOST_ROOT_PATH environment variable, ensure that the root path is included in the path of your callback URL.
  4. Use the optional configuration variables documented above to customize behavior such as display names, sign-up policies, group-based access control, and more.

Configuring LDAP Authentication

Phoenix supports authentication against LDAP directories, including:
  • Microsoft Active Directory
  • OpenLDAP
  • 389 Directory Server
  • Any LDAP v3 compliant directory
LDAP authentication allows users to log in with their corporate directory credentials, enabling centralized user management and integration with existing identity infrastructure.
LDAP (Lightweight Directory Access Protocol) is the industry-standard protocol for accessing directory services. Phoenix uses LDAP to authenticate users against your corporate directory and optionally map directory groups to Phoenix roles.
LDAP support requires Phoenix 12.20.0 or later.

​
Required LDAP Configuration

To enable LDAP authentication, set the following environment variables in addition to PHOENIX_ENABLE_AUTH and PHOENIX_SECRET:
Environment VariableDescription
PHOENIX_LDAP_HOSTLDAP server hostname or IP address. Comma-separated for multiple servers with automatic failover. (Required)

Examples:
• Single server: ldap.corp.example.com
• Multiple servers: dc1.corp.com,dc2.corp.com,dc3.corp.com
PHOENIX_LDAP_USER_SEARCH_BASE_DNSJSON array of base DNs (Distinguished Names) for user searches. Phoenix searches each base DN in order until a user is found. (Required)

Examples:
• Active Directory: [“OU=Users,DC=corp,DC=example,DC=com”]
• OpenLDAP: [“ou=people,dc=example,dc=com”]
PHOENIX_LDAP_GROUP_ROLE_MAPPINGSJSON array mapping LDAP groups to Phoenix roles. Must contain at least one mapping (Phoenix will fail to start if empty).

Example (grant all authenticated LDAP users MEMBER): [{“group_dn”:”*”,“role”:“MEMBER”}]
PHOENIX_LDAP_ATTR_EMAILLDAP attribute containing the user’s email address (e.g., mail). Set to null to enable authentication without email (see warning below for additional required settings).

​
Optional LDAP Configuration

Environment VariableDescription
PHOENIX_LDAP_PORTLDAP server port. Defaults to 389 for StartTLS or 636 for LDAPS based on PHOENIX_LDAP_TLS_MODE.
PHOENIX_LDAP_TLS_MODETLS connection mode. Options:
• starttls (default): Upgrade plaintext connection to TLS on port 389
• ldaps: TLS from connection start on port 636
• none: No encryption (testing only, credentials sent in plaintext)
PHOENIX_LDAP_TLS_VERIFYVerify server TLS certificates. Defaults to true. Should always be true in production to prevent MITM attacks.
PHOENIX_LDAP_TLS_CA_CERT_FILEPath to custom CA certificate file (PEM format) for TLS verification. Use when your LDAP server uses a private/internal CA not in the system trust store.

Example: /etc/ssl/certs/internal-ca.pem
PHOENIX_LDAP_TLS_CLIENT_CERT_FILEPath to client certificate file (PEM format) for mutual TLS authentication. Requires PHOENIX_LDAP_TLS_CLIENT_KEY_FILE to also be set.
PHOENIX_LDAP_TLS_CLIENT_KEY_FILEPath to client private key file (PEM format) for mutual TLS authentication. Requires PHOENIX_LDAP_TLS_CLIENT_CERT_FILE to also be set.
PHOENIX_LDAP_BIND_DNService account DN for binding to the LDAP server. Optional. When set, PHOENIX_LDAP_BIND_PASSWORD must also be set.

Example: CN=svc-phoenix,OU=Service Accounts,DC=corp,DC=com
PHOENIX_LDAP_BIND_PASSWORDService account password for binding to the LDAP server. Should be stored securely (e.g., in a Kubernetes Secret).
PHOENIX_LDAP_USER_SEARCH_FILTERLDAP filter for finding users. Use %s as placeholder for the username.

Defaults to Active Directory format: (&(objectClass=user)(sAMAccountName=%s))

OpenLDAP example: (&(objectClass=inetOrgPerson)(uid=%s))
PHOENIX_LDAP_ATTR_DISPLAY_NAMELDAP attribute containing user’s display name. Defaults to displayName.
PHOENIX_LDAP_ATTR_MEMBER_OFLDAP attribute containing group memberships. Defaults to memberOf. Used when PHOENIX_LDAP_GROUP_SEARCH_FILTER is not set (Active Directory mode).
PHOENIX_LDAP_ATTR_UNIQUE_IDLDAP attribute containing an immutable unique identifier. Required when PHOENIX_LDAP_ATTR_EMAIL is null (users are identified by this ID instead of email). Also recommended if you expect user emails to change frequently (e.g., due to name changes or company rebranding).

Options:
• Active Directory: objectGUID
• OpenLDAP: entryUUID
• 389 DS: nsUniqueId
PHOENIX_LDAP_GROUP_SEARCH_BASE_DNSJSON array of base DNs for group searches. Required when PHOENIX_LDAP_GROUP_SEARCH_FILTER is set.

Example: [“ou=groups,dc=example,dc=com”]
PHOENIX_LDAP_GROUP_SEARCH_FILTERLDAP filter for finding groups containing a user. Use %s as placeholder for the user identifier.

Two modes:
• AD Mode (not set, recommended for Active Directory): Reads the memberOf attribute directly from the user entry. AD automatically populates this.
• Search Mode (set): Searches for groups in PHOENIX_LDAP_GROUP_SEARCH_BASE_DNS. Required for POSIX groups (posixGroup) or when memberOf is unavailable.

Example: (&(objectClass=posixGroup)(memberUid=%s))
PHOENIX_LDAP_GROUP_SEARCH_FILTER_USER_ATTRLDAP attribute from the user entry to substitute for %s in PHOENIX_LDAP_GROUP_SEARCH_FILTER. Only used when PHOENIX_LDAP_GROUP_SEARCH_FILTER is set.

When set: Reads the specified attribute from the user’s LDAP entry
When not set (default): Uses the login username directly

Understanding group membership attributes:
• POSIX groups (memberUid): Contains usernames like “jdoe”. Use default (login username) or uid.
• groupOfNames (member): Contains full DNs. Requires distinguishedName (Active Directory only—OpenLDAP does not expose DN as an attribute).

Common values:
• Not set (default): Uses login username (works for POSIX groups)
• uid: Explicitly use uid attribute
• distinguishedName: Full DN (Active Directory only)
PHOENIX_LDAP_ALLOW_SIGN_UPAllow automatic user creation on first LDAP login. Defaults to true. Set to false to require pre-provisioned users (created via PHOENIX_ADMINS or the UI before first login). Note: Setting to false requires email to be configured (PHOENIX_LDAP_ATTR_EMAIL), as pre-provisioned users are matched by email address.
LDAP Directories Without Email AddressesIf your LDAP directory does not have the mail attribute (or any email attribute), set PHOENIX_LDAP_ATTR_EMAIL=null to enable authentication without email. When this mode is enabled:
  • PHOENIX_LDAP_ATTR_UNIQUE_ID is required — users are identified by this immutable ID instead of email
  • PHOENIX_LDAP_ALLOW_SIGN_UP must be true — users are auto-provisioned on first login (pre-provisioning by email is not possible without email addresses)
  • PHOENIX_ADMINS cannot be used — use PHOENIX_LDAP_GROUP_ROLE_MAPPINGS to assign admin roles instead
  • Users will appear in Phoenix without email addresses — the UI will display username instead of email where applicable
# Example: LDAP without email (Active Directory)
export PHOENIX_LDAP_ATTR_EMAIL=null
export PHOENIX_LDAP_ATTR_UNIQUE_ID=objectGUID
export PHOENIX_LDAP_ALLOW_SIGN_UP=true
export PHOENIX_LDAP_GROUP_ROLE_MAPPINGS='[{"group_dn":"CN=Phoenix Admins,OU=Groups,DC=corp,DC=com","role":"ADMIN"},{"group_dn":"*","role":"MEMBER"}]'

# Example: LDAP without email (OpenLDAP)
export PHOENIX_LDAP_ATTR_EMAIL=null
export PHOENIX_LDAP_ATTR_UNIQUE_ID=entryUUID
export PHOENIX_LDAP_ALLOW_SIGN_UP=true
export PHOENIX_LDAP_GROUP_ROLE_MAPPINGS='[{"group_dn":"cn=admins,ou=groups,dc=example,dc=com","role":"ADMIN"},{"group_dn":"*","role":"MEMBER"}]'

OpenLDAP Configuration Example

# Enable authentication
export PHOENIX_ENABLE_AUTH=true
export PHOENIX_SECRET=your-secret-key-at-least-32-chars

# LDAP server connection
export PHOENIX_LDAP_HOST=ldap.example.com
export PHOENIX_LDAP_PORT=636
export PHOENIX_LDAP_TLS_MODE=ldaps

export PHOENIX_LDAP_GROUP_SEARCH_BASE_DNS='["ou=groups,dc=example,dc=com"]'
export PHOENIX_LDAP_GROUP_SEARCH_FILTER="(&(objectClass=posixGroup)(memberUid=%s))"
# PHOENIX_LDAP_GROUP_SEARCH_FILTER_USER_ATTR not set - uses login username by default

export PHOENIX_LDAP_GROUP_ROLE_MAPPINGS='[{"group_dn":"cn=admins,ou=groups,dc=example,dc=com","role":"ADMIN"},{"group_dn":"*","role":"MEMBER"}]'

​
Active Directory with Nested Groups

For Active Directory environments using nested groups with the member attribute (which contains full DNs):
Recommended approach: Start with the simpler AD Mode (read the user’s memberOf attribute; leave PHOENIX_LDAP_GROUP_SEARCH_FILTER unset). This is usually easiest to configure, but it typically only includes the user’s direct group memberships (not “group-in-group” / nested groups).If your authorization relies on nested groups, use search mode with Active Directory’s LDAP_MATCHING_RULE_IN_CHAIN (OID 1.2.840.113556.1.4.1941) as shown below, or flatten group memberships in AD.
# Enable authentication
export PHOENIX_ENABLE_AUTH=true
export PHOENIX_SECRET=your-secret-key-at-least-32-chars

# LDAP server connection
export PHOENIX_LDAP_HOST=ldap.corp.example.com
export PHOENIX_LDAP_TLS_MODE=starttls

# Service account
export PHOENIX_LDAP_BIND_DN="CN=svc-phoenix,OU=Service Accounts,DC=corp,DC=example,DC=com"
export PHOENIX_LDAP_BIND_PASSWORD="service-account-password"

# User search
export PHOENIX_LDAP_USER_SEARCH_BASE_DNS='["OU=Users,DC=corp,DC=example,DC=com"]'
export PHOENIX_LDAP_USER_SEARCH_FILTER="(&(objectClass=user)(sAMAccountName=%s))"

# Nested group search using LDAP_MATCHING_RULE_IN_CHAIN (AD-specific OID)
# The member attribute contains full DNs, so we need distinguishedName
export PHOENIX_LDAP_GROUP_SEARCH_BASE_DNS='["DC=corp,DC=example,DC=com"]'
export PHOENIX_LDAP_GROUP_SEARCH_FILTER="(member:1.2.840.113556.1.4.1941:=%s)"
export PHOENIX_LDAP_GROUP_SEARCH_FILTER_USER_ATTR="distinguishedName"

# Group to role mapping
export PHOENIX_LDAP_GROUP_ROLE_MAPPINGS='[{"group_dn":"CN=Phoenix Admins,OU=Groups,DC=corp,DC=example,DC=com","role":"ADMIN"},{"group_dn":"*","role":"VIEWER"}]'

​
LDAP with Multiple Servers (Failover)

For high availability, configure multiple LDAP servers: 
export PHOENIX_LDAP_HOST="dc1.corp.com,dc2.corp.com,dc3.corp.com"
Phoenix will try each server in order until a successful connection is established.
Multi-server failover behavior:Phoenix assumes all configured servers are replicas with identical user sets. Failover only occurs on connection errors:
ConditionBehavior
Server unreachable / timeout✅ Tries next server
User not found❌ Returns immediately (no failover)
Invalid password❌ Returns immediately (no failover)
Not supported: Multi-domain or multi-forest Active Directory configurations where different users exist on different servers. In these environments, users can only authenticate against the first reachable server that contains their account.This design provides faster authentication, better security (no probing of multiple servers), and avoids masking infrastructure issues like replication lag.

​
LDAP with Custom CA Certificate

When your LDAP server uses a certificate signed by an internal CA: 
export PHOENIX_LDAP_TLS_CA_CERT_FILE=/etc/ssl/certs/internal-ca.pem

​
LDAP with Mutual TLS (Client Certificates)

For environments requiring client certificate authentication: 
export PHOENIX_LDAP_TLS_CLIENT_CERT_FILE=/etc/ssl/certs/phoenix-client.crt
export PHOENIX_LDAP_TLS_CLIENT_KEY_FILE=/etc/ssl/private/phoenix-client.key

​
Disabling Password Authentication (LDAP-Only)

To require all users to authenticate via LDAP and disable local password authentication: 
export PHOENIX_DISABLE_BASIC_AUTH=true
export PHOENIX_LDAP_HOST=ldap.corp.example.com
export PHOENIX_LDAP_USER_SEARCH_BASE_DNS='["OU=Users,DC=corp,DC=example,DC=com"]'
export PHOENIX_LDAP_ATTR_EMAIL=mail
export PHOENIX_LDAP_GROUP_ROLE_MAPPINGS='[{"group_dn":"*","role":"MEMBER"}]'
# ... other LDAP settings
LDAP Security Best Practices:
  • Always use TLS encryption (PHOENIX_LDAP_TLS_MODE=starttls or ldaps) in production
  • Always verify TLS certificates (PHOENIX_LDAP_TLS_VERIFY=true) in production
  • Store the bind password securely (e.g., Kubernetes Secrets, HashiCorp Vault)
  • Use a dedicated service account with minimal read-only permissions
  • Configure group role mappings to follow the principle of least privilege
User Identity: By default, Phoenix identifies LDAP users by their email address. Configure PHOENIX_LDAP_ATTR_UNIQUE_ID to use an immutable identifier like objectGUID (Active Directory) or entryUUID (OpenLDAP) if:
  • Your LDAP directory does not have email addresses (set PHOENIX_LDAP_ATTR_EMAIL=null)
  • You expect user emails to change frequently (e.g., due to company rebranding or name changes)

​
Advanced Authentication Configuration

The following optional environment variables provide additional control over authentication behavior for advanced use cases:
VariableDescription
PHOENIX_ADMIN_SECRETA secret key that can be used as a bearer token instead of an API key. It authenticates as the first system user (admin). This key must be at least 32 characters long, include at least one digit and one lowercase letter, and must be different from PHOENIX_SECRET. Additionally, it must not be set if PHOENIX_SECRET is not configured.

Usage: Authorization: Bearer <PHOENIX_ADMIN_SECRET>
PHOENIX_DISABLE_BASIC_AUTHForbid login via password and disable the creation of local users, which log in via passwords. This can be helpful in setups where authentication is handled entirely through OAuth2. Defaults to False.
PHOENIX_DISABLE_RATE_LIMITDisable rate limiting for login attempts. Defaults to False. Use with caution as this removes brute-force protection.
PHOENIX_ACCESS_TOKEN_EXPIRY_MINUTESThe duration, in minutes, before access tokens expire. Defaults to the system default if not specified.
PHOENIX_REFRESH_TOKEN_EXPIRY_MINUTESThe duration, in minutes, before refresh tokens expire. Defaults to the system default if not specified.
PHOENIX_PASSWORD_RESET_TOKEN_EXPIRY_MINUTESThe duration, in minutes, before password reset tokens expire. Defaults to the system default if not specified.
PHOENIX_ADMINSA semicolon-separated list of username and email address pairs to create as admin users on startup. The format is username=email, e.g., John Doe=john@example.com;Doe, Jane=jane@example.com. The password for each user will be randomly generated and will need to be reset. The application will not start if this environment variable is set but cannot be parsed or contains invalid emails. If the username or email address already exists in the database, the user record will not be modified. Changing this environment variable for the next startup will not undo any records created in previous startups.
PHOENIX_ROOT_URLThis is the full URL used to access Phoenix from a web browser. This setting is important when you have a reverse proxy in front of Phoenix. If the reverse proxy exposes Phoenix through a sub-path, add that sub-path to the end of this URL setting.

⚠️ WARNING: When a sub-path is needed, you must also specify the sub-path via the environment variable PHOENIX_HOST_ROOT_PATH. Setting just this URL setting is not enough.

Examples:
• With a sub-path: https://example.com/phoenix
• Without a sub-path: https://phoenix.example.com
PHOENIX_MANAGEMENT_URLThe URL to use for redirecting to a management interface that may be hosting Phoenix. If set, and the current user is within PHOENIX_ADMINS, a link will be added to the navigation menu to return to this URL.
