Windows Hello lets you sign into Windows 10 devices with your face or finger
Microsoft is backing biometric authentication in a big way today with the unveiling of a new feature named Windows Hello. Microsoft’s upcoming Windows 10 operating system will support Windows Hello, allowing you to sign into a machine with just your face or finger. Windows Hello works by scanning your face, iris, or fingerprint to unlock devices, replacing a PIN or password to gain access to your own machine.
