Windows Hello – biometric authentication which can provide instant access to your Windows 10 devices.* 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. And not only is Windows Hello more convenient than typing a password—it’s more secure! Our system enables you to authenticate applications, enterprise content, and even certain online experiences without a password being stored on your device or in a network server at all.
