Windows Hello is one of the new features in Windows 10, which was released by Microsoft last month. This kind of technology allows you to sign into your PC with just your face. The service, which works by using a RealSense 3D camera made by Intel, is very fast at detecting your face. However, there are always security concerns over Windows 10’s facial recognition, which Microsoft claims is “much safer than traditional passwords.” So how good is it?


The answer is: good enough that even twins can’t fool it. The Australian has conducted an informal test where six closely matched twin pairs tried fooling the system’s biometric security. In each pair, only one twin would register her/his face and then the other attempted to access the windows 10 machine equipped with RealSense by standing in front of it.

Then how did Microsoft’s latest operating system do?

Even twins can’t trick Windows 10s facial recognition.


The result is that it worked too well. The software could distinguish between the twins with impressive accuracy. It wasn’t tricked once, even when the unregistered twin tried to fool the camera by removing his/her glasses or fixing his/her hair. This suggests that the face detection is reliable enough and quite good in Windows 10.

“It could distinguish between us two quite easily,” said Miriam Jeffrey, one of the twins who failed to fool the technology. “It’s a little surprising, I thought it would have failed, but no, it was really good, it was really quick.”

Windows Hello is available to all those who have Windows 10 and a compatible camera. In addition to the face detection feature, the password-alternative system, which even works in the dark, lets you authenticate into your device using fingerprints. With Windows Hello, neither you have to remember a password nor you worry much about your evil twin or doppelganger accessing your computer.
