I know very little about cybersecurity and cryptography, but wouldn't it make sense for each device have a different passcode associated with a touch id? For example, my iPhone has a passcode XXXXXX, with touch ID associated with it. At the same time, my Macbook has a passcode 0123456789 with a touch ID associated with it.
