Deleting old device users, like employees who left or switched locations, can help to clean up your login page. Go to the Account & Settings tab in Poynt HQ and click on Device Users.
The ability to delete will appear next to the users that are eligible (you can only delete users who are managers or employees, not users).
Simply select x and agree to the prompt.
Note: You cannot delete the currently logged in user. You will always need to have at least one terminal user to process transactions.
