Windows Hello is a more personal, more secure way to get instant access to your Windows 10 devices using fingerprint, facial recognition, or a secure PIN. Most PC's with fingerprint readers already work with Windows Hello, making it easier and safer to sign into your PC. Windows Hello lets you sign in to your devices, apps, online services, and networks using your face, iris, fingerprint, or a PIN. Even if your Windows 10 device can use Windows Hello biometrics, you don’t have to. If it’s the right choice for you, you can rest assured that the info that identifies your face, iris, or fingerprint never leaves your device. Windows does not stores pictures of your face, iris, or fingerprint on your device or anywhere else. When you set up Windows Hello biometrics, it takes the data from the face camera, iris sensor, or fingerprint reader and creates a data representation—or graph—that is then encrypted before it’s stored on your device.
