Touch ID to FR Transition Phase

Maybe iOS will automatically replace TouchID with facial recognition. Wherever Touch ID was used now you'd use FR... That's how I'm thinking it will work. It's Touch ID version 2.0.

 

No, such functionality has to be built inside the particular app to be utilized.
The OS doesnt replace security measures put there by individual apps.
It might take some time for most apps to be updated with that added feature, I think most big companies will get on it quick though.

 

There's three scenarios:

1) OS will show a facial recognition prompt instead of TouchID whenever apps request TouchID on the OLED/X/Edition iPhone.
2) OS will not show a facial recognition prompt, and fall back to a passcode prompt instead of facial recognition whenever apps request TouchID on the OLED/X/Edition iPhone.
3) Apps will crash or stop working because TouchID doesn't exist on OLED/X/Edition iPhone.

Most likely it will be (1) but could also be (2). I don't think Apple will let apps crash or stop working when they request TouchID, that would be bad for user experience. Plus they would've announced support for facial recognition in SDK at WWDC so apps can be updated to use it, although they might announce it during the keynote (updates to BiometricKit to support facial recognition) so devs can update their apps in time for OLED iPhone release.

 

So surely that means that developers will have to have two versions of their app. If i want to access my bank app, I use touch id but if i upgrade to the iphone 8, there will have to be a different app to use facial recognition.

 

No, one version of the app but has to be updated to include all available devices that could access it.
Just built in functionality to recognize the type of device you're using and offer the available sign in options.

 

Did TouchID immediately replace wherever your passcode was used before? For banks in particular, they have to really buy into the security of the feature before they will implement it. So there will likely be a transition period. If there really is no TouchID in the "iPhone 8" that may mean a step backwards to using passcodes again for many apps.

 

I think Face ID will replace Touch ID in such apps.

 

I think Face ID will have to be built into apps by developers. I think this is why (or in large part) iOS 11 has a new feature which allows users to save passwords for apps. This was likely prioritized because they new they needed to ease the aggravation that losing the instantaneous security method of Touch ID would bring.

 

As I suspected....
