When a user forgets his account password, you can recover it. If an administrator forgets a password, you can reset the password back to admin / admin. You can also change passwords.
Note that there is no way to recover if a user forgets his private password (if enabled). Read more here.
Use the Recover Password command if a user has forgotten his account password. This command sends an email message with a link to the Account page where the user can change his password.
Use the My Profile page to change your password.
You can reset the SYSADMIN login back to admin / admin.
You will need the first 5 characters of your Master License Key.

The script is located in the PRO Server command line tools directory of your CrashPlan PRO Server application.
