Perhaps I am missing something. Are you saying TouchID aalows you to register multiple fingerprints for access to a device? With regards to the kids ignoring your requirement to not have passcodes. Well, what can I say, my kids do as i say, perhaps a different approach is in order? For example, my kids know they should not play any computer games during the week. On Saturdays they can play as much as they want. During the week it's academics, mindstorms and good old-fashion go outside and get dirty play. I've never had to enforce the rule. In general terms i think kids respond well to rules and schedules so long as these things are fairly and consistently applied.
