Windows Hello allows you to gain instant access to your Windows 10 devices via fingerprint, facial recognition or a secure pin code. This makes it more personal and secure. Windows Hello is compatible with most PCs equipped with fingerprint readers, making it safer and easier to sign in to your computer. Windows Hello allows you to sign in to your devices and apps, online services, networks, and services using your face, fingerprint, iris, or a pin. You don't have the Windows Hello biometrics enabled on your Windows 10 device. If you decide it is the right choice, you can rest assured that your information that identifies you face, iris, and fingerprint will never leave your device. Windows does not store any pictures of your face, fingerprint, or iris on your device. Windows Hello biometrics takes data from your fingerprint reader, face camera, or iris sensor and creates a data representation (or graph) that is encrypted before it is stored on your device.
