Don't think of Touch ID as unlocking the phone.
You know how you can "sudo" and type your password (if you have an account with sudo privileges) and then for a few minutes afterward you don't have to type your password when you use sudo?
Think of Touch ID like that: the passcode is still the thing that unlocks the phone, but once it's been entered you can use Touch ID for a little while, in much the same way that sudo can remember you've recently proved yourself to it. After 48 hours, after a certain number of failed Touch ID attempts, or after any restart of the phone, though, Touch ID stops being available and the phone goes back to only being unlockable via the passcode (Touch ID will only become available after the next time the passcode is entered).
- basch 11y agothat is what i am asking, where is the 48 hour part. ive never left my phone untouched for 48 hours, except in a powered off state.

- cstejerean 11y agoYou don't have to leave the phone untouched for 48 hours. Even if you touch it you still need the passcode every 48 hours. TouchID only works for 48 hours past the last passcode login.
- huxley 11y agoNot quite, the passcode is needed 48 hours past the last unlock but the clock restarts with every login or unlock including TouchID unlocks.
- tedd4u 11y agobasch what happens is, at a minimum, the iPhone requires your PIN or passcode every 48 hours to unlock. In between, you can use your finger as many times as you want. So the 48 hour timer should fire as soon as immediately after someone gets posession of your phone, but no more than 48 hours afterward.
- basch 11y agothat is not true, I dont type my pin in every 2 days. from what I read, the device has to be left in a locked state for 48h.
- rhizome 11y agoJust as a point of reference, Android has a feature by which you can register locations at which a PIN is not required. I've registered my home (which is not super secure, since GPS resolution means it works anywhere in my apartment building), and I have to input the PIN every morning because the interval resets every 4 hours.
