How can I return to login screen after screensaver??

I am trying to set up my Parents new Mac like their old Windows XP machine. When the Windows PC sat idle it went to screensaver and if the mouse was moved it returned to the login screen with their user icons.
On the Mac the option under Security "Require password after screensaver" will bring up a password prompt for the user who is currently logged in with a "Switch User" button.
Hitting that "Switch User" button will bring me to the login screen with the list of users and their icons. Does anyone know of a way where it will bypass prompting for a password and goto the login screen without hitting the "Switch Users" button?

it's possible but what's wrong with hitting "switch user"? that's really the easiest. anything else will require extra work. see this link
