With Windows 10 a new way of logging in is added. With Windows 8 you could login with your Microsoft Account, a PIN code or(especially handy for Tablets) a Picture password. With a fingerprint reader you also could login with your fingerprint.
Now there is also logging in with you face added. You need a Real Sense camera for this. There are already some laptops available with this camera build in. It should be possible later to login with a Kinect Sensor v2.
In this small (Dutch) movie a small impression.
Cool he!
