Microsoft today announced a new feature in Windows 10 called ‘Windows Hello’. Windows Hello allows users to unlock their systems using their face, iris or fingerprint. With Windows Hello, you’ll be able to just show your face, or touch your finger, to new devices running Windows 10 and be immediately recognized.
Windows Hello introduces system support for biometric authentication – using your face, iris, or fingerprint to unlock your devices – with technology that is much safer than traditional passwords. You– uniquely you– plus your device are the keys to your Windows experience, apps, data and even websites and services – not a random assortment of letters and numbers that are easily forgotten, hacked, or written down and pinned to a bulletin board. Modern sensors recognize your unique personal characteristics to sign-you-in on a supporting Windows 10 device.
As this is a hardware dependent feature,you need new Windows 10 devices that supports Windows Hello. You might think unlocking using face will allow others to use your photo to unlock the device. 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. Also, for facial or iris detection, the cameras use infrared technology to identify your face or iris and can recognize you in a variety of lighting conditions.
