To enable log in with a social network you need to enable social login for your realm and configure one or more social providers.

To configure social login, open the Keycloak Admin Console, select your realm from the drop-down box in the top left corner. In the Login Options section click on Social login to set it to ON. Click save settings, then click on Social in the menu at the top. To enable a social provider select the provider you want from the drop-down and click on Add Provider. Then continue to the section below that provides specific instructions for the provider you are adding.

It's possible to configure a realm to only allow social login. To do this open the Keycloak Admin Console, select your realm from the drop-down box in the top left corner. Click the Credentials tab, and click on the x next to password in the Required User Credentials. This will disable login with username and password.

There is a single callback url used by all realms and social providers. This makes it possible to share the configuration for a social network between multiple realms. An example callback url is http://localhost:8080/auth/rest/social/callback. To get the callback url for your server replace http://localhost:8080 with the base address of your server. You can also find the callback url in the Keycloak Admin Console under social settings.
