One of the most talked about features of the Apple iPhone X is definitely the Face ID feature. As Apple explains, this feature identifies hundreds of details on your face in order to securely unlock your phone when you’re looking at it. While the feature has already been a part of many privacy-related debates, it has now been put through a ‘Twin test’ to check the accuracy of Apple’s new biometric security system.

Both Mashable and Business Insider ran separate ‘twin tests’ to check whether the iPhone X unlocks the phone for identical twins. Mashable’s test started by asking two sets of identical twins to try out the feature. In both the cases, one twin registers their face on the iPhone X, and then unlocks the device. Then the device is locked again, and the second twin holds up the iPhone X to see if they could unlock it. In both instances, the iPhone X successfully unlocked using the face of the non-registered twin, fooling Face ID completely. Further, in the video, a twin brother was asked to remove his glasses and had the other brother registered, however, this time again, the Face ID failed to tell the difference.

Business Insider‘s test results has different results though. The test followed the same process of having one twin register his face, and the other try to unlock it. The registered twin further unlocked the phone wearing a hat, glasses, and a scarf. However, when the second twin tried to unlock the phone it failed to unlock the phone, leaving the twins puzzled.

During the Face ID demo at the Steve Jobs Theater, Apple claimed that chances of someone bypassing Face ID are one in a million. Aldo recently, Craig Federighi, Apple’s senior vice president of Software Engineering had said that “Face ID provides intuitive and secure authentication enabled by the TrueDepth camera system and the A11 Bionic chip, which uses advanced technologies to accurately map and match the geometry of a user’s face.”

The iPhone X is up for pre-orders via e-commerce sites as well as authorized Apple resellers. In terms of pricing, the Apple iPhone X is available in two variants. The 64GB storage version of iPhone X is priced at Rs 89,000, while the higher-end 256GB model comes at Rs 102,000. The smartphone will go on sale in India starting November 3.
