How is it worse than a password in that way?
You can't use a cryptographic hash, as small changes in a password means it's wrong, but in biometrics it needs to be allowed to account for different angles/lighting/mood. This means there must be more accessible information on the device.
you can't change your fingerprint, unlike a leaked password
My understanding is that your fingerprint cannot be recreated from the data on the iPhone at least, and that it never leaves the touchID module. Is that wrong?
