KeyLock

When working on your computer, chances are that you do not like it when other users look over your shoulder and take a peek at your emails, chat messages or the website you are currently browsing.

Since people get even more curious when you leave your desk for a few minutes, you can rely on specialized apps such as KeyLock to lock your PC and prevent unauthorized usage.

Once you download and install the application, you will be required to choose a removable drive that will become your so-called ‘unlock device.’ You also get the possibility to define several such devices, without too much of a hassle.

When it comes to defining the unlock device, you basically need to browse through all your connected drives and select the one you are interested in.

Another handy function of KeyLock is that it can personalize the way your computer screen looks like when you have locked it.

Namely, you can apply a custom wallpaper as well as choose one of the available styles (such as Windows Classic, XP, 7, 8 or 10). Several colors are also available and you even get to compose a special message that is displayed on your locked screen - thus, you can warn other users that the PC cannot be accessed until the correct device is connected, so they should not bother trying.

If you are working on a laptop, you are surely trying to save battery power as much as possible, and KeyLock can help achieve that. You can set the app to lock the PC, then automatically dim the screen, slow down the response time or remove the background after a certain time.

KeyLock can be a nifty app to have around when you want to make sure nobody tampers with your documents while you are away from the PC. It can be quickly configured even by users with little PC skills, so as to lock and unlock their PC by simply plugging or removing an USB flash drive.
