If you mistype the admin password and attempt to login in three times in a row the account will be locked. That is one reason it is highly recommended to have another account with administrative rights so the other account can be used to unlock the admin account and reset the password.
If the admin account is locked, but you know its password, simply restart Maestro and it will automatically be unlocked. Please see the instructions in the Starting and Stopping the Maestro Project Server section.
In the case of an admin account that is locked and its password has been forgotten perform the following steps:
Note: You must have another administrative account to perform these steps.
In the case that you have also forgotten the password of the other administrative account or you don't have another account with administrative rights, you can delete the user database from the operating system, then when you start Maestro it will prompt you to set the password and other information for the admin account.
Note: All users will have to be manually added back to Maestro after this procedure.
