authentik configuration

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

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.
     • Add three Strict redirect URIs and set them to app.immich:///oauth-callback, https://immich.company/auth/login, and https://immich.company/user-settings.
     • Select any available signing key.
   • 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.
   • Configure Launch URL (optional): set the Launch URL to https://immich.company/auth/login?autoLaunch=1 to allow automatic login to Immich when clicking on the application from within authentik.

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