Set Screen Saver Security sets the time until the screen saver activates, and whether a password is required to unlock the screen saver.
Every company I’ve worked for that had an office also had a rule that any computer in the office had to be password-protected with a screensaver that kicked in pretty quickly. But at home it’s annoying to have to unlock your own laptop when you get up to make a sandwich.
If you use the same computer at home and in the office, IMLocation can use this action to lock down your computer at work, but leave it easy-to-use at home.
I recommend trying IMLocation (which includes the Set Screen Saver Security action) for best results.
