I don want anyone to create new user accounts by themselves, for security reasons. How do I disable user registration?
You can’t disable user registration entirely. However, you can configure YouTrack the way that once a new user account is registered, it doesn’t get any permissions at all – that is, until an administrator grants them. To do that: • Click Groups in the Admin area. • Clear any check boxes that are selected in Auto Join column. • For any projects with unavailable Auto Join check box, click the name of a project. • In the Groups > [Group name] page, click Roles. • Click Unassign for all roles listed in the Roles tab.
