Navigate to the **Admin Area > Settings > General**. 1. Expand the **Sign-in restrictions** section. ## Password authentication enabled You can restrict the password authentication for web interface and Git over HTTP(S): - **Web interface**: When this feature is disabled, an [external authentication provider](../../../administration/auth/README.md) must be used. - **Git over HTTP(S)**: When this feature is disabled, a [Personal Access Token](../../profile/personal_access_tokens.md) must be used to authenticate. ## Two-factor authentication When this feature enabled, all users will have to use the [two-factor authentication](../../profile/account/two_factor_authentication.md). Once the two-factor authentication is configured as mandatory, the users will be allowed to skip forced configuration of two-factor authentication for the configurable grace period in hours. ![Two-factor grace period](img/two_factor_grace_period.png) ## Email notification for unknown sign-ins > [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/218457) in GitLab 13.2. When enabled, GitLab notifies users of sign-ins from unknown IP addresses or devices. For more information, see [Email notification for unknown sign-ins](../../profile/unknown_sign_in_notification.md). ![Email notification for unknown sign-ins](img/email_notification_for_unknown_sign_ins_v13_2.png) ## Sign-in information All users that are not logged-in will be redirected to the page represented by the configured "Home page URL" if value is not empty. All users will be redirect to the page represented by the configured "After sign out path" after sign out if value is not empty. In the Sign-in restrictions section, scroll to the "Sign-in text" text box. You can add a custom message for your users in Markdown format. For example, if you include the following information in the noted text box: ```markdown # Custom sign-in text To access this text box, navigate to Admin Area > Settings > General, and expand the "Sign-in restrictions" section. ``` Your users will see the "Custom sign-in text" when they navigate to the sign-in screen for your GitLab instance: ![Sign-in page](img/custom_sign_in_page_v13_6.png)
