Back in October 2012 when Microsoft officially launched the new Windows 8, the company also introduced a new authentication system called picture password.
Specifically designed for touchscreen devices
, picture passwords are based on gestures set up by the administrator and then used to unlock any unit running Windows 8.
While this could indeed be a revolutionary way to protect a Windows 8 computer, a new research conducted by Arizona State University, Delaware State University and GFS Technology
shows that picture passwords are rather unsafe and could be easily hacked.
