One I mentioned in Section 2.
Your biometric, your fingerprint or your face,
are simply as strong as the passcode that's behind it.
Apple actually makes this a little bit easier for us,
because we can see that it shows us
how many digits are expected in the passcode,
whereas Android does not.
So here, we can see this is a four-digit PIN.
Four-digit PIN is the weakest and the easiest to crack.
A six-digit PIN is obviously more complex.
A passcode is going to require dictionary files
to be brute forcely run against those items.
