authentik configuration

To support the integration of Arcane with authentik, you need to create an application/provider pair in authentik.

Create custom scope mapping

Arcane either requires the email scope to return a true value for whether the email address is verified, if account merge is enabled. As of authentik 2025.10 the default behavior is to return email_verified: False, so a custom scope mapping is required for Arcane to allow authentication.

1. Log in to authentik as an administrator and open the authentik Admin interface.

2. Navigate to Customization > Property Mappings and click Create.

   • Select type: select Scope Mapping.

   • Configure the Scope Mapping: Provide a descriptive name (e.g. Arcane Email Scope), and an optional description.

     • Scope name: email
     • Expression:
     pythonCopy

     return {
         "email": request.user.email,
         "email_verified": True
     }
     

3. Click Finish to save the property mapping.

Create an application and provider in authentik

1. Log in to authentik as an administrator and open the authentik Admin interface.

2. Navigate to Applications > Applications and click Create with Provider to create an application and provider pair. (Alternatively you can first create a provider separately, then create the application and connect it with the provider.)

   • Application: provide a descriptive name, an optional group for the type of application, the policy engine mode, and optional UI settings.
   • Choose a Provider type: select OAuth2/OpenID Connect as the provider type.
   • Configure the Provider: provide a name (or accept the auto-provided name), the authorization flow to use for this provider, and the following required configurations.
     • Note the Client ID, Client Secret, and slug values because they will be required later.
     • Set a Strict redirect URI to https://arcane.company/auth/oidc/callback.
     • Select any available signing key.
     • Under Advanced protocol settings:
       • Remove the authentik default OAuth Mapping: OpenID 'email' scope, and add the custom scope mapping you created above.
   • Configure Bindings (optional): you can create a binding (policy, group, or user) to manage the listing and access to applications on a user's My applications page.

3. Click Submit to save the new application and provider.

Arcane configuration

To configure Arcane to use authentik, add the following environment variables to your Arcane deployment:

OIDC_ENABLED=true
OIDC_CLIENT_ID=<client_id>
OIDC_CLIENT_SECRET=<client_secret>
OIDC_ISSUER_URL=https://authentik.company/application/o/<application_slug>/
OIDC_MERGE_ACCOUNTS=true # Match first SSO login to existing account by email
OIDC_SCOPES="openid email profile"

Then restart Arcane to apply the changes.
