The leaked version of Windows 10 (build 10125) includes the first preview of Windows Hello. Microsoft recently rolled out a new version of its operating system, but only a few days after the release, Windows 10 build 10125 manage to escape the walls of Redmond. The new build include a few changes, including the arrival of Microsoft new security feature called Windows Hello.

Windows Hello is a new feature in Windows 10 that allows users to sign-in using facial recognition eliminating the need of passwords. While the feature is now already present in the operating system, it does require special hardware with IR sensors to make it all work securely without storing a password on the device or in a network server.

The setup of Windows Hello is very straightforward, just like creating a PIN or changing an account password. Simply go to Settings, navigate to Accounts, and on Sign-in options, you’ll find a new area called “Windows Hello”.

Then click the Set up button and the “Windows Hello Setup” will launch, then click Get started, verify your PIN, and follow the on screen directions. Note that due to the fact that I’m running a virtual machine and the PC doesn’t have the require hardware, I can’t yet fully test this new feature.

The new feature includes two options that users can customize: The first options allows users to automatically unlock the screen as soon as Windows Hello recognize your face, and the second option enables users to add an extra level of security by requiring to turn your head left and right to unlock Windows 10.
