When Apple debuted Face ID with the iPhone X in 2017, it claimed it was even more secure than Touch ID. While this might be true, the biggest issues with Face ID are that it is slower than Touch ID and despite being more secure, it could be easily bypassed by one’s identical twin brother or sister.
For the 2018 iPhone XS series, Apple has only made claims of Face ID being faster than ever and that it is still more secure than Touch ID. Yet again though, as tests conducted by twin brothers running the LifeofTwinz YouTube channel show, Face ID on the iPhone XS still unlocks if one identical brother registers their face and another tries to unlock the phone.
Face ID was also fooled when one identical twin tried opening the iPhone XS Max with a beard. That seemed to have made little to no impact as Face ID still unlocked the device. In the third test, the identical twins wore a hat and then tried to open the same iPhone XS Max. And once again, they were able to do so successfully.
To Apple and Face ID’s credit though, the company had said last year that identical twins might be able to bypass Face ID. Plus, the identical twins in the video really do look identical so Face ID getting confused between them should be forgiven.
