KeyLemon is a biometric computer lock that uses your voice or face as the key.

Experience a new way to login with face and/or speaker recognition instead of typing your username and password. It replaces the standard Windows logon screen with a KeyLemon login screen that connects to your webcam. You simply set up your webcam and run through the KeyLemon's setup wizard which runs you through the process step by step. One thing to note is the facial picture setup is very touchy and you need to have good lighting as well as a steady cam set up or you will spend a bit of time on that step. You will also need to know your Windows password to complete the setup of KeyLemon.

If for whatever reason you are not recognized and identified, KeyLemon will still allow you to login manually or switch back to the standard Windows interface.
