Not so identical after all

Windows Hello

Bad news for evil twins -- it doesn't look like you'll be able to use your face to bypass your twin's security in Windows 10, provided he or she is taking advantage of Windows Hello, a biometric authentication scheme that provides instant access to Windows 10 devices.

For systems that support it, Windows Hello takes the place of punching in passwords, allowing you to use your mug (or fingerprint) to log into Windows and authenticate applications, enterprise content, and even some online experiences. Systems equipped with an Intel RealSense 3D camera (F200) can use the facial unlock feature, and based on some recent testing, it does a good job even at discerning between identical twins.

To test the feature, The Australian rounded up half a dozen sets of identical twins and had them use Windows Hello on a Lenovo ThinkPad Yoga 14. The laptop has an Intel RealSense camera embedded above the display, which contains an infra-red lens, a regular lens, and a 3D lens.

While the sample size is small, in each case, Windows Hello was successful in keeping non-account holders from logging in. It didn't matter if the non-account holder wore his or her hair the same way as their twin, Windows Hello wouldn't let them in.

The limited testing bodes well for Intel and Microsoft, though the technology isn't perfect. One of the twins initially had trouble getting Windows Hello configured, and in another instance, it failed to work altogether. In other cases, it would sometimes take a bit of time to identify a twin, though it never let a non-account holder gain access to the laptop.
