An administrator can log in to ISPmanager with the permissions of another user to view the panel as the account owner. To do so, go to User accounts → Administrators, Users or FTP-users → Login.
The administrator with the superuser permissions can log in as an Administrator and User. The administrator without superuser permissions can access the panel only as a User. To switch back to the previous User level, open the drop-down list in the upper right corner of the interface and click on the <username>.
