I was looking at the iPhone 5S which is very nice, but the finger print reader is a non-starter. If someone wants to unlock your phone, you can't deny them entry as your fingerprints can't be "forgotten". What I would like to do is use the fingerprint and password on the phone (not passcode. A full 8+ character passWORD) to ensure it is impossible to unlock without both my fingerprint and my password. How do I set this up?
