Lock & unlock your computer screen with Lemonscreen

Maybe I have seen too much of Star Trek and other sci-fi series on television but there is something about being able to lock and unlock something with your face or your voice. It kind of makes your text password pale in comparison when all you have to do is sit down in front of your monitor and your face is all that’s needed to unlock your screen.

That’s precisely what Lemonscreen does. It’s a small program for Windows XP only that scans your face with your webcam, saves the scan in its memory and then uses that face scan to lock and unlock your PC. When you go to set it up, you have to sit in front of your webcam, press the button and let it scan you, making sure that your face is inside the little red square.
