re: Apple Fingerprint Hack: A Great Reminder
I must admit, I'm really skeptical about this argument. Functionally, I think it's a lot easier to surreptitiously see what code I'm repeatedly putting into my phone all day than it would be to make a latex replica of my finger. And when we're talking about mobile phones, we really don't have a great way of doing multi-factor authentication unless we can bring two quite different things together.
Ultimately, having both TouchID and a passcode would be quite secure from a practical standpoint. Theoretically, perhaps not, but I'm a practitioner, not an academic.
Oh, and I did get a 5S last Friday, and I can say that from a usability standpoint, TouchID is excellent.
