If you are using Manager’s server edition and forget the password for the administrator, you will be unable to log in under the Username
administrator. So you will not be able to create new users or modify permissions. Attempting to log in without a valid password will return a warning:
To regain access, you must reset the administrator password. Follow these instructions:
Find the file named password
and delete it. This will remove the password from the administrator
account.
Go back to the login screen, enter the Username
administrator, and click Login (Do not enter anything into the Password
field).
Once you log in, set a new password in the Users tab so no-one will be able to access your server as administrator without entering a password.
To reset the administrator’s password for the cloud edition, go to the cloud edition customer support page. See this Guide for information.
