Windows Hello is a more personal way to sign in to your Windows 10 devices with just a look or a touch. You’ll get enterprise-grade security without having to type in a password.
Surface Pro 4, Surface Book, and most PCs with fingerprint readers already work with Windows Hello, and more devices that can recognize your face and fingerprint will be available in the future. You can also sign in to your PC using Windows Hello companion devices, such as Microsoft Band and some Windows 10 phones.
Select the Start button, then select Settings > Accounts > Sign-in options to set up Windows Hello. Under Windows Hello , you’ll see options for face, fingerprint, or iris if your PC has a fingerprint reader or a camera that supports it. Once you’re set up, you’ll be able to sign in with a quick swipe or glance.
You might be asked to add a PIN before you can set up Windows Hello.
