Removing administrator accounts
You can remove an administrator's account when you want to permanently get rid of it. As an alternative, you can disable an administrator's account which prevents access to the account.
To remove an administrator's account:
On the top navigation panel, click administration.
Select the administrator whose account you want to remove, then click overview.
On the action bar above the administrator information form, click Remove.
Verify the account that you are removing, then click OK.
The account is removed. If the administrator is currently logged in to the control panel, a message stating that the account has been disabled is displayed when they attempt any action.
