More about Auto Logoff
Screen Pass extends the capability of the standard workstation lock and gives network administrators control over idle workstations. You can enforce screensaver password use, screensaver timeout, and screen saver selection. Advanced features include automatic logout and shutdown, customizable administrator override, and auditing of all logon/logoff and lock/unlock events.
Screen Pass is tested, scanned, and monitored frequently to assure it is free of spyware, adware, viruses, and other malicious programs.
