Microsoft is bringing native biometric security to users in Windows 10, so you can use facial recognition, fingerprints or iris recognition to login to your device. These features will be available using "Windows Hello".
TechRepublicWindows Hello works by scanning your face, iris, or fingerprint and then logging you into your device. Of course, fingerprint recognition has been around for quite a while, and there are a host of fingerprint readers currently on the market that provide biometric security access to Windows computers. However, the current crop of fingerprint readers requires additional software. With Windows Hello, the biometric security feature will be supported natively, and Microsoft claims that Windows 10 will support existing fingerprint readers. How many it will support and to what extent remains to be seen.
