Windows 10's Hello feature provides a wide selection of methods to log in for your laptop, from passwords to PIN numbers, fingerprint scans and even facial recognition. That latter requires an infrared or Intel RealSense camera. So far, that's been limited to select computers, like Microsoft's own Surface Book and HP's EliteBook Folio G1. You can also buy some external webcams that will provide this functionality.

It is cool, and it works really well. If you have the right hardware, here's how you can setup Windows Hello's face login:

1. Open Settings and choose Accounts.

2. Click "Sign-in options" on the sidebar and scroll right down to Windows Hello. Click "Set up" under Face.

Without having a PIN, you'll need to set that up first. That's located directly above Windows Hello.

3. Click Get Started.

4. Enter your PIN.

5. Stare into the webcam while Windows Hello scans the face. This process will be quick.

6. Click Improve Recognition for additional scans, or close the setup process. If you wear glasses or perhaps a hat, we recommend that you scan the face with and without one on.

The next time you sign in to Windows, the camera will be hunting the face.
