[Feature Request] Unlock with fingerprint #366

Closed trackktor closed 2 years ago

trackktor commented 5 years ago

Hello, It is me again.

With a lots of bank app it is possible to unlock with fingerprint instead of scheme or pin. It is REALLY convenient and really improve the user experience.

Maybe it could be added to samourai ?

To go further you could add a fingerprint check for send or any dangerous operations if there is a fingerprint sensor (same idea as Feature request: ask for PIN before sending a transaction). It could be particularly usefull when you are switching between apps and Samourai stay open.

Here, two examples of existing bank app 20190915_213411 Screenshot_20190915-211822_CMSO

It may be convenient, but it's considered insecure. That's probably enough reason for the samourai wallet developers not to implement it.

We will not be using any biometric capabilities in Samourai Wallet.

Why don't we close this issue?

I think this is a sad oversight. If our goal is to maximize security, then at least a passphrase option should be allowed. A 5-6 digit PIN just spells trouble. I wonder how many people just use their birthday or a significant other's birthday as the PIN.

I really suggest reading the white paper on TouchID from Apple or documentation for Android developers. Your actual fingerprint images aren't stored in the phone itself, and there's no way to extract a fingerprint.
