+## Clear authentication tokens for all users. Important! Data loss!
+
+Clear authentication tokens for all users in the GitLab database. This
+task is useful if your users' authentication tokens might have been exposed in
+any way. All the existing tokens will become invalid, and new tokens are
+automatically generated upon sign-in or user modification.
