Microsoft will let you unlock Windows 10 with your face

Microsoft overnight introduced Windows Hello, a Windows 10 feature that will allow users to login into their computers using face, iris and fingerprint recognition. Windows Hello will be compatible with existing fingerprint scanners for fingerprint recognition, but will rely on specialised hardware for face and iris recognition.

"For facial or iris detection, Windows Hello uses a combination of special hardware and software to accurately verify it is you – not a picture of you or someone trying to impersonate you," Microsoft corporate vice president Joe Belfiore said on the company's Windows blog. "The cameras use infrared technology to identify your face or iris and can recognize you in a variety of lighting conditions."

Intel's RealSense 3D Camera will support Windows 10's facial and iris unlock functionality. Devices including the ASUS ROG G771JM, ASUS X751LD, Dell Inspiron 15 5548 and Lenovo ThinkPad Yoga 15 all currently feature RealSense.
