KeyLemon: A Free Face Recognition Software


KeyLemon uses face recognition feature, instead of requiring you to type your username and password thereby providing a simple solution to log on to your personal Windows account.

One of the main features of the application is ‘Hijackers Tacking’. The feature helps you to retrieve information about who tried to access your computer in your absence or when you were away.

KeyLemon also works as a password manager for many of the popular websites. When you connect to say Facebook, Twitter or LinkedIn, KeyLemon automatically logs you into your account by using your face – no matter if your computer has multiple users. When you leave the computer, it automatically locks your computer once you are away and unlocks it only when you are back – using your face.

KeyLemon will also let you know:
  • Who was present in front of your computer before automatic windows lock
  • Who typed a wrong password when computer was locked

The program has the ability to replace the standard Windows logon screen with a KeyLemon login screen that connects to your webcam. The latest version KeyLemon 2.5 for Windows comes with two main new features:


  • Multiple face model management 
  • Anti-spoofing check for login
