Windows 10 arrived with many interesting features on board, with one of them being Windows Hello, a better way to login to your Windows machine through biometrics, be it a fingerprint or facial recognition, for authentication. Initial Surface Pro 4 review units given to people didn’t come with support for Windows Hello, and were told that a software update in the future will enable the feature for the Surface Pro 4 and the Surface Book.
If you’ve received your Surface Pro 4, you should get a firmware update as well which enables Windows Hello support on the device, allowing you to use biometrics instead of traditional passwords (via AnandTech).
To get it up and running, just head over to Settings > Accounts > Sign-in options. Firstly, you’ll be asked to set up a password as well as PIN. Later, under the Windows Hello section, you can either use facial recognition, fingerprints or iris as the authentication method if you have the compatible hardware.Microsoft, Surface Book, Surface Pro 4, Windows 10, Windows Hello
