You would expect a complicated set of options stored in a difficult interface. KeyLemon is such an application and lets you access any of your accounts simply by showing your face. What's more, technology now allows software to detect face patterns with intelligent associations with yourself or friends and family. Not necessarily for surveillance purposes, but it takes social networking to a whole new level. Nonetheless, you can still download it from Softpedia and use it with the limitations listed on this page While it is now impossible to purchase the application.
Note: KeyLemon is no longer supported and the developer cannot provide trial licenses extensions or free licenses for the application.
