Locking and unlocking a Redmine user

Updated on 2024-08-01  •  Created on 2023-03-31  •  ISHIHARA Yukiko

When a Redmine user stops using Redmine, for example because of a transfer or retirement, "lock" the user so that the user cannot access Redmine.

Redmine has two features that stop a user from accessing Redmine: "Lock" and "Delete". If you delete a user, information such as the history of the issues that the user updated loses the name of the user. If you lock a user, the history remains and the user cannot access Redmine.

Lock Delete
  • The name of a locked user is shown in gray in history such as issue comments
  • A locked user is no longer shown in the list of project members or in the drop-down menu for selecting the Assignee
  • If you unlock the user, the user can start using Redmine again at any time
  • The name disappears from the information about issues that the deleted user created or updated
  • The Assignee of the issues that were assigned to the deleted user becomes blank
  • The deleted user is shown as "Anonymous", and you can no longer see who updated an issue
  • You cannot restore a deleted user
