Unless you're in the habit of cleaning your phone after every single use your fingerprints are already on the device. Case 2 has different dimensions than what is stated.
Although most like the convenience of using a fingerprint to unlock, it would be nice to have the option of turning it into a form of pseudo keypad by requiring two to thee different fingerprints in sequence. That should make it a bit more secure as well as misdirecting those that assume the types of security.
Here's what I want. A very quick and preferably non-obvious / grossly apparent way to trigger my touch ID enabled phone to force prompt for passcode/word.
Push the power button thrice. Touch with a different finger. Whatever. Something that takes a second, involves no "obvious" movements or none that can be stopped part way through, and that disables touch sign-on until I actually enter the passcode/word.
Will it stop someone rubber hosing me? No. Will it hinder BS like the above? Maybe. (Especially when I have a few moments to react before the aggressor gets to me.)
I would like phones to support a duress finger. If you try to unlock with your duress fingerprint, it disables fingerprint access, requiring your long password.
While this is a cool technical solution the problem is not technical, it's political. Even if it existed, utilizing this function could result in legal reprocussions.
