A new feature in Windows 10, Windows Hello brings biometric security to the new operating system from Microsoft. This feature eliminates the need to login into any Windows device using passwords, and is definitely a more secure way to sign in to your Windows 10 device, app or a service. This post will show you how to use Windows Hello in Windows 10 to sign in.
Windows Hello supports facial recognition and works by scanning the iris. It also supports fingerprints. The highlight of it is the Infrared Technology support, that allows the facial recognition feature to work in almost all kinds of lighting situations. The departure from the normal behavior of having to enter password every time you login is thus very welcome.
