No, it only means that the device reported a match; or, that a match signal came in on a certain hardware port (since the scanner may have been replaced, tamperered with, etc.).
- mrtksn 4y agoNot necessarily, it depends on the implementation. On Apple's case AFAIK the fingerprint mach doesn't simply report a match but also provides the system with the key(which was stored in a separate system) to decrypt the data. You can't simply connect a bogus fingerpront scanner to an Apple device and access the system, in fact that's the reason why unauthorised repairs end up having the touch ID or Face ID broken.
