I'm assuming this is supposed to be metaphorical but you don't seem to understand that it is not analogous because replacing FaceID doesn't suddenly give you access to the device.
It absolutely could, if the processor trusts that the data coming from the faceid sensor is accurate, the faceid sensor can simply lie. You’re removing a layer of defense, which necessarily impacts security
What’s the faceid sensor going to do, brute force a damn cryptographic collision with the cyphertext of your faceid?!
If you have even the first fucking clue, even in the broadest of strokes, I’d really be interested in hearing about how this would actually work.
I think he think the face id just says "yeah, that's right, unlock" and the phone unlocks. So if you put in a custom one that always says "yeah unlock" it will just always unlock. As if the person putting in the thing couldn't see the data on your storage anyway
