Correct me if I'm wrong, but isn't it also possible to just use one of your fingers that you didn't register with touch ID for 5 or so consecutive unlock attempts and it will have the same effect as rebooting your phone?
- notjosh 10y agoThere is a slight difference. Keychain and NSFileManager have possible modes of "kSecAttrAccessibleAfterFirstUnlock" [0] and "NSFileProtectionCompleteUntilFirstUserAuthentication" [1] respectively that are (fittingly) in an open state within your app after you've unlocked the device.
