This trick probably won’t be used that often, but it might be nice to have if you get stuck. If you have a Mingle installation that isn’t configured to send out emails and you have forgotten your password for some reason, you can change your password if you’ve got access to the database.
mysql> update users set lost_password_key = 123, lost_password_reported_at = CURRENT_TIMESTAMP where login = your_username;
Once you do that, you can go to this URL (substitute values for your installation):
That will let you reset your password.
