KeyLemon is a simple solution to log on to your personal Windows account by using your face. If your computer has multiple users, the software automatically logs you into the right account. When you leave the computer, it will automatically lock it and then unlock it when you are back. It also tracks your face evolution by saving automatically one image day after day. You can then export and share this movie with your friends.

KeyLemon protects your Windows computer against hijackers (permanent protection) and allows you to unlock (or resume from sleep) with face recognition. Just download the software, create your face model, and unlock your session simply and conveniently with KeyLemon. How does it work? The app is a simple solution that checks that you are behind your computer. When you leave the computer, it will automatically lock it and then unlock it when you are back. It takes a picture of the hijackers who tried to access your computer when you leave it.
