Choosing an authentication method for Log in at Walk Up causes the MFP to require everyone
to log in for access to the control panel menus. You can choose to require further authentication for
specific functions of the MFP.
Choose an authentication method for each device function as desired. If you choose to use
different log in methods for each device function, the MFP will require authentication as
needed. The MFP automatically allows authenticated users to continue whenever they are
allowed to use a feature.
