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.
If your device already has a fingerprint reader, you’ll be able to use Windows Hello to unlock that device. 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. The cameras use infrared technology to identify your face or iris and can recognize you in a variety of lighting conditions.
