+#### Login providers

+##### Local login
+
+With this setting, you control if the local login form is shown on the login page or not. By default, the local login form is shown and users an login into the site as normal. If you disable this setting, the local login form is hidden. This allows you to just provide login buttons for external identity providers like OAuth2 or OIDC.

+##### IDP login intro
+
+With this setting, you control if the 'Log in using your account on' intro is shown above the IDP login buttons or not. By default, the intro is shown and users will be quickly informed what the IDP buttons are about. If you disable this setting, the IDP intro is hidden. This allows you to provide a clean user login interface if you just use external identity providers like OAuth2 or OIDC.
