Apple introduced Face ID on iPhone all the way back in 2017, and Touch ID quickly became absent from all but the budget iPhone SE. Now, the SE is about to lose it too. But I think its actually the perfect time to bring Touch ID back across the entire iPhone lineup, and Vision Pro is why.Vision Pro made me instantly miss Touch ID on iPhoneVision Pro is perhaps Apples most advanced technological achievement.Yet very shortly after buying this spatial computer, I immediately wanted Apple to bring a piece of legacy tech back: Touch ID.Why?Because Face ID on iPhone does no good when Vision Pro is strapped to your facean unfortunate detail Im reminded of every time I use visionOS.Ill admit that Im a new Vision Pro owner, so maybe this is just a problem of rewiring my brain to stop reaching for my iPhone.Maybe one day, Ill be such a visionOS ninja that Ill no longer rely on the iPhone at all when using Vision Pro.But I really doubt it.The iPhone isnt going away any time soon. So my desire to use the iPhone while wearing Vision Pro wont either.Perhaps Apple can update Face ID in software to authenticate my face even while wearing a Vision Pro.The company shipped a similar software fix in 2022 when masks were more common. It made Face ID less secure, but far more convenient for COVID days.I imagine that making Face ID work for Vision Pro wearers would be much more difficult. Thus, Touch ID could be the solution.There are other advantages to having Touch ID on iPhone, too, as some have pointed out. In certain situations, its more convenient than Face ID.Touch ID fix isnt urgent, but it will grow more important over timeRight now, Vision Pro is only, per CEO Tim Cook, an early adopter product. So early adopter annoyances like this one shouldnt dictate Apples priorities.or... Apple could just allow iPhone to unlock when wearing Apple Vision Pro.My Mac unlocks when I'm wearing my Watch. My phone unlocks with my watch and I'm wearing a face mask.If I'm wearing Apple Vision Pro, then AVP literally knows when I look at my phone and my phone knows when I'm wearing AVP. They can do a handshake and unlock. We don't need to bring back an old authentication method when there's solutions.But then also... No on has AVP so Apple didn't even prioritize that feature. They could have had that day one but there's so much missing from visionOS that's the least of our problems. View all commentsBut some time in the next few years, before Vision products become more of a thing, I really hope Touch ID can make its triumphant return to the iPhone.Under-display Touch ID would be great. But Apple doesnt need to overdo it. Just add the feature into the power button, like whats available on iPad.Apple devices are known for working especially well together, so I hope this key exception can get fixed before long, and Vision Pro and iPhone can stop getting in each others way.Do you think Apple should bring Touch ID back to the iPhone?
