Some of you may know this situation:
You sit around your computer with some guys and really, really need to go to toilet or something but you don’t want that these guys play with your computer/laptop.
So you lock your screen and went away. As soon as your back you type in your password (hopefully no one will see it). Maybe its really long and takes some time. Wouldn’t it be great your computer locks itself if you went away and unlocks if your back?
No problem!
