Pretty sure this is not true. That’s how apple’s fingerprint scanners work. On android the fingerprint data is stored either in the tpm or a part of the storage encrypted by it.
Yeah, so the app never sees it. What are you disagreeing with?
I just corrected that, can’t I without disagreeing?
I mean that I don’t know what part of my comment is “not true”. I welcome corrections, I just don’t see what is being corrected here.
It doesn’t send a yes/no signal it sends the fingerprint to be compared to the stored one

The app gets either the
onAuthenticationSucceededoronAuthenticationFailedcallback. It doesn’t get the fingerprint.Edit: I think we are misunderstanding each other, I’m saying that apps never see the fingerprint. The OS does, depending on the device.
