Windows Hello is a more personal way to sign in to Windows 10 devices. It uses iris recognition to verify your identity, which means you get enterprise-grade security without having to type in a password.
The Lumia 950 and 950 XL are ready to use Windows Hello now, and more devices supporting Windows Hello will be available in the future.
On Start , swipe over to the All apps list, then select Settings > Accounts > Sign-in options.
Once you're set up, you'll be able to unlock your phone at a glance.
