Android appears to do something like this with fingerprints (or at least enable it). Whenever I add a new one, apps stop accepting fingerprints until I enter my password/passcode/whatever in each one.
- cassianoleal 3y agoThat's ok but in this case it won't help since the attacker already has the phone's passcode.
- Tommstein 3y agoIf each app has its own password/passcode that you can bypass with your fingerprint, and fingerprints suddenly stop working, it absolutely does shut down the thief, unless you also use the phone's passcode for all your accounts.
- cassianoleal 3y agoOh I see. On the iPhone though, FaceID / TouchID are the same as the passcode - at least in the sense that if the biometrics fail, they fall back to the passcode. This means that if you enable log in with biometrics, you’re essentially enabling the fallback along even if the app has a separate PIN/passcode.
- Shadowmist 3y agoI just tried it on my iPhone with a banking app and it shows me the default login screen for the bank and then logs me in if my face is there, but without the face it just stays on the login screen waiting for me to enter the bank password, never asks for a PIN.
- cassianoleal 3y agoHuh, I just tried this with a couple of my bank apps and they do the same. I guess either I'm misremembering this, or it got fixes along the way. Wallet is still accessible with the device passcode as a fallback though, which means quite a lot of damage can still be done.
