9to5Mac: Face ID coped fine with CPAP masks on older iPhones, all the way back to the iPhone X.

Apple prides itself on its accessibility features, but a British man who wears a CPAP mask due to respiratory failure says that something appears to have gone wrong with either the company’s more compact TrueDepth camera system, or the iOS changes designed to guard against spoofing.

Colin Hughes, an Apple user who has severe muscular dystrophy, has to wear the mask for much of the day. He said that Face ID used to work reliably for him with or without the mask, but that is not the case with the iPhone 13 Pro.
