KeyLemon software (version 2.7.1) is a face recognition software that allows users to log in to their computer by using facial recognition technology. The software can be used with a webcam or a built-in camera on a computer. It also offers the option to create multiple user profiles and can be configured to lock the computer when the user steps away from the camera. Additionally, KeyLemon software provides security by automatically logging out users when they are no longer in front of the computer.
