Personally, I think it would be a cool possibility to require BOTH faceid and touchid. I would not use it, but having the possibility is neat. I love faceid, and hope it only keeps getting better. The combo would have to make the most ardent defenders of privacy happy, no?

Thing is, with both there is no reason to not use both. You shouldn't have to scan your face and your thumb to unlock your phone. The one that makes most sense in the current situation should be good enough. Ex. you pick up your phone without touching the screen and the screen wakes up. Face ID triggers and you are in. Or you have it on your table and tap to wake the screen, Touch ID will handle it this time and you have unlocked your device. In a situation where Face ID fails, just tapping something on the display will then unlock with Touch ID.

It should be seamless to the user and you shouldn't even be thinking about that you have to unlock your phone. It's just aways "unlocked" to you.

It could even work the other way around. Someone takes your phone and starts using it, during use Touch ID senses something is wrong and initiates a Face ID scan. Both verify it isn't you and the device locks. This could be user configurable of course as sometimes you want to hand your device to someone else

That would be cool. It could ping over to my watch and ask if I wanted to lock the phone or something.

No, that's two points of failure. Imagine you've just jumped out of a pool. FaceID goes fine, but Touch ID fails because your finger it wet. You fix that problem, but now have the sun directly on your face so this time around Face ID fails. It could take a frustrating experience and make it horrible. I can't imagine it requiring BOTH to succeed to unlock the phone. That might be great for those who have a genuine need for the best security possible, but Apple doesn't really seem to concern themselves overly much with niche groups of users. If they added both, I would expect either method would be adequate to unlock the phone, but it wouldn't require both. And knowing Apple, setting it for both wouldn't even be an option.

The only real way to know if Apple will introduce a finger print reader under the display, would probably be early/mid 2020 right when manufacturing would start in June for the latest iPhone leaks start to form. I still think face ID will be predominate through 2020, and I don’t for see a fingerprint reader under the display being a reality maybe until 2021, if Apple decides to change biometric security forms, which at that point, would be five years with Face ID total from when it was first introduced with the 2017 iPhone X.

They aren’t eliminating Face ID just because Touch ID is coming back. They want 3 forms of security(passcode,face,fingerprint) for future passport and government issued IDs stored on iPhones. It’s just added security, Not eliminating one for the other this time. And I am guessing they are axing 3D Touch to make room for Touch ID.

I bet it could be set for both. But there would be 3 forms of authentication. Passcode as well. Their plans are for government issued identification to be stored on the phone and will require 2 forms of biometric authentication. So if it can be set for that I’m sure it would be for unlocking too. Then they get to set a new support charge. *Unlocking device’s after idiots get locked out both ways fee*

Do you have a source for claiming government issued Id on phones require two different forms of biometric authentication.

I didn't mean to say that the phone would require both, just that you could decide to require both. Poor wording on my part!
