OAuth Authentication

This page contains details about using OAuth in Immich.

tip

Unable to set app.immich:/ as a valid redirect URI? See Mobile Redirect URI for an alternative solution.

Overview

Immich supports 3rd party authentication via OpenID Connect (OIDC), an identity layer built on top of OAuth2. OIDC is supported by most identity providers, including:

• Authentik
• Authelia
• Okta
• Google

Prerequisites

Before enabling OAuth in Immich, a new client application needs to be configured in the 3rd-party authentication server. While the specifics of this setup vary from provider to provider, the general approach should be the same.

1. Create a new (Client) Application

   1. The Provider type should be OpenID Connect or OAuth2
   2. The Client type should be Confidential
   3. The Application type should be Web
   4. The Grant type should be Authorization Code

2. Configure Redirect URIs/Origins

   The Sign-in redirect URIs should include:

   • app.immich:/ - for logging in with OAuth from the Mobile App
   • http://DOMAIN:PORT/auth/login - for logging in with OAuth from the Web Client
   • http://DOMAIN:PORT/user-settings - for manually linking OAuth in the Web Client

   Redirect URIs should contain all the domains you will be using to access Immich. Some examples include:

   Mobile

   • app.immich:/ (You MUST include this for iOS and Android mobile apps to work properly)

   Localhost

   • http://localhost:2283/auth/login
   • http://localhost:2283/user-settings

   Local IP

   • http://192.168.0.200:2283/auth/login
   • http://192.168.0.200:2283/user-settings

   Hostname

   • https://immich.example.com/auth/login
   • https://immich.example.com/user-settings

Enable OAuth

Once you have a new OAuth client application configured, Immich can be configured using the Administration Settings page, available on the web (Administration -> Settings).

Setting	Type	Default	Description
Enabled	boolean	false	Enable/disable OAuth
Issuer URL	URL	(required)	Required. Self-discovery URL for client (from previous step)
Client ID	string	(required)	Required. Client ID (from previous step)
Client Secret	string	(required)	Required. Client Secret (previous step)
Scope	string	openid email profile	Full list of scopes to send with the request (space delimited)
Signing Algorithm	string	RS256	The algorithm used to sign the id token (examples: RS256, HS256)
Storage Label Claim	string	preferred_username	Claim mapping for the user's storage label¹
Storage Quota Claim	string	immich_quota	Claim mapping for the user's storage¹
Default Storage Quota (GiB)	number	0	Default quota for user without storage quota claim (Enter 0 for unlimited quota)
Button Text	string	Login with OAuth	Text for the OAuth button on the web
Auto Register	boolean	true	When true, will automatically register a user the first time they sign in
Auto Launch	boolean	false	When true, will skip the login page and automatically start the OAuth login process
Mobile Redirect URI Override	URL	(empty)	Http(s) alternative mobile redirect URI

Claim Options [1]

Claim is only used on user creation and not synchronized after that.

info

The Issuer URL should look something like the following, and return a valid json document.

• https://accounts.google.com/.well-known/openid-configuration
• http://localhost:9000/application/o/immich/.well-known/openid-configuration

The .well-known/openid-configuration part of the url is optional and will be automatically added during discovery.

Auto Launch

When Auto Launch is enabled, the login page will automatically redirect the user to the OAuth authorization url, to login with OAuth. To access the login screen again, use the browser's back button, or navigate directly to /auth/login?autoLaunch=0.

Mobile Redirect URI

The redirect URI for the mobile app is app.immich:/, which is a Custom Scheme. If this custom scheme is an invalid redirect URI for your OAuth Provider, you can work around this by doing the following:

1. Configure an http(s) endpoint to forwards requests to app.immich:/
2. Whitelist the new endpoint as a valid redirect URI with your provider.
3. Specify the new endpoint as the Mobile Redirect URI Override, in the OAuth settings.

With these steps in place, you should be able to use OAuth from the Mobile App without a custom scheme redirect URI.

info

Immich has a route (/api/oauth/mobile-redirect) that is already configured to forward requests to app.immich:/, and can be used for step 1.
