Apple Face ID fails to distinguish brothers

Occurred: November 2017

Two brothers with similar though not identical facial features posted a video to Reddit showing Apple's Face ID facial recognition system failing to distinguish them. The incident raises questions about the reliability of Apple's Face ID system.

The video showed the brother who had set up Face ID on his new iPhone X showing the feature working properly for him. His brother then tried to unlock the same phone without wearing glasses, and was rejected, but unlocked the device when he donned glasses similar in style to his brother.

Face ID had been shown to struggle in several other scenarios, including distinguishing identical twins.
