- Go to Console>Global Settings>Administrators
- Select the Administrator account on which you want to reset the password - make sure they are not using "External" (Windows NT/LDAP) authentication
- Right click on the Administrator account:
- In the Properties window select the "Authentication" tab (make sure the type selected is "Internal" and the account does not authenticate through "External" means such as Windows Active Directory)
-

- Enter the "New Password"
- Re-enter the "Confirm New Password"
- Click "OK" at the bottom
Now the password for that Administrator account has been successfully changed.
¯\_(ツ)_/¯
