When Apple debuted Face ID with iPhone X’s introduction, they said that even though the probability of someone else unlocking iPhone X with Face ID is 1 in a 1,000,000, they warned identical twins may unlock each other’s iPhone using Face ID.

Now, it seems twins are no longer needed.

A woman in Nanjing, China found out that her colleague can unlock her iPhone using Face ID. She is said to have retrained Face ID several times but her colleague was still able to access her iPhone X.

When she first reported the matter to Apple, she was told that what was happening was “impossible”. She was eventually given a refund after she demonstrated the flaw to Apple store employees.

She bought a second iPhone X and still the same flaw was exhibited.
