Admins can update roles and restrictions to user accounts from within 'Passport'. Firstly navigate to the 'Accounts' tab and select the user that needs to be updated via the 'View' button. You will be able to click on the 'edit' button to update fields on a users profile from names to the default account. You will also have the ability to delete the profile if you would like to remove access forever. To delete the account click on the red 'delete' button to the right of the screen.
