KeyLemon is a simple solution to log on to your personal Windows account by using your face. If you computer has multiple users the software automatically logs you into the right Windows account. When you leave the computer, it will automatically lock it and then unlock it when you are back. KeyLemon works as a password manager for popular internet sites. When you connect to a website (Facebook, Twitter and / or LinkedIn), KeyLemon automatically logs you into your account by using your face. Experience a new way to login by face recognition instead of typing your username and password. It replaces the standard Windows XP / Vista logon screen with a KeyLemon login screen that connects to your webcam. If you want to you can have fun by customising your welcome screen with your own background image or theme.
