FYI: Yeah, the cops can force your finger onto a suspect's iPhone to see if it unlocks, says judge

Authentication factors

1) Something you know (password)

2) Something you have (key)

3) Something you are (biometrics)

What this is looking like is only 'something you know' is legally protected. A 'something you have' can be forcibly taken and used to authenticate (a key & a lock). Biometrics are new in mainstream usage.

What it looks like is courts are determining the 'something you are' can be forcibly taken and used as authentication.
