+### Third-party authentication example
+Keycloak is a popular IAM solution and integration is straight forward thanks to Django Allauth. This example can also be used as reference for other third-party authentication solutions, as documented by Allauth.
+
+At Keycloak, create a new client and assign a `Client-ID`, this client comes with a `Secret-Key`. Both values are required later on. Make sure to define the correct Redirection-URL for the service, for example `https://tandoor.example.com/*`. Depending on your Keycloak setup, you need to assign roles and groups to grant access to the service.
+
+To enable Keycloak as a sign in option, set those variables to define the social provider and specify its configuration:
+```ini
+SOCIAL_PROVIDERS=allauth.socialaccount.providers.keycloak
+SOCIALACCOUNT_PROVIDERS='{ "keycloak": { "KEYCLOAK_URL": "https://auth.example.com/", "KEYCLOAK_REALM": "master" } }'
+```
+
+1. Restart the service, login as superuser and open the `Admin` page.
+2. Make sure that the correct `Domain Name` is defined at `Sites`.
+3. Select `Social Application` and chose `Keycloak` from the provider list.
+4. Provide an arbitrary name for your authentication provider, and enter the `Client-ID` and `Secret Key` values obtained from Keycloak earlier.
+5. Make sure to add your `Site` to the list of available sites and save the new `Social Application`.
+
+You are now able to sign in using Keycloak.

 ### Linking accounts
 To link an account to an already existing normal user go to the settings page of the user and link it. 
 Here you can also unlink your account if you no longer want to use a social login method.
