Grafana are using short-lived tokens as a mechanism for verifying authenticated users. These short-lived tokens are rotated each for an active authenticated user.

An active authenticated user that gets it token rotated will extend the login_maximum_inactive_lifetime_duration time from “now” that Grafana will remember the user. This means that a user can close its browser and come back before now + login_maximum_inactive_lifetime_duration and still being authenticated. This is true as long as the time since user login is less than login_maximum_lifetime_duration.

Remote logout

You can logout from other devices by removing login sessions from the bottom of your profile page. If you are a Grafana admin user you can also do the same for any user from the Server Admin / Edit User view.

Settings

Anonymous authentication

You can make Grafana accessible without any login required by enabling anonymous access in the configuration file. For more information, refer to Implications of allowing anonymous access to dashboards.

Example:

  1. [auth.anonymous]
  2. enabled = true
  4. # Organization name that should be used for unauthenticated users
  5. org_name = Main Org.
  7. org_role = Viewer
  9. # Hide the Grafana version text from the footer and help tooltip for unauthenticated users (default: false)
  10. hide_version = true

If you change your organization name in the Grafana UI this setting needs to be updated to match the new name.

Basic auth is enabled by default and works with the built in Grafana user password authentication system and LDAP authentication integration.

Disable login form

You can hide the Grafana login form using the below configuration settings.

  1. [auth]
  2. disable_login_form = true

Set to true to attempt login with OAuth automatically, skipping the login screen. This setting is ignored if multiple OAuth providers are configured. Defaults to false.

Hide sign-out menu

Set the option detailed below to true to hide sign-out menu link. Useful if you use an auth proxy or JWT authentication.

URL to redirect the user to after signing out from Grafana. This can for example be used to enable signout from oauth provider.
