+Grafana uses short-lived tokens as a mechanism for verifying authenticated users.
+These short-lived tokens are rotated on an interval specified by `token_rotation_interval_minutes` for active authenticated users.
 
-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.
