DF/Manager allows multiple users to have their own account. Users should be in the Administrators group to have full access to DF/Manager. The groups Members and Moderators are reserved for future use. 

DF/Manager has a built-in administrator account (the name of this account can be set during installation, the default is admin). Built-in accounts cannot be deleted.

The administrator can change passwords for all other users, including the admin account. There is a password recovery function in case the administrator loses his/her own password. Passwords cannot be retrieved from the database as they are stored encrypted for security reasons.
