I'll be honest, I never saw finger print scanning as the next security measure, it was always about convenience to me. It's the same with PIN numbers, all someone has to do is stand next to you to see your PIN number and they are good to go.

True security comes from multiple layers of security, where the question changes randomly but you still know what the end result will be, much like a bank does when signing in.

When things become easier, it only remains easy to get in to it. The reason it isn't so easy right now is because it hasn't had to be so widely available. When TouchID becomes more popular, you will read more stories on how people have found easier ways of cracking it.

It's all about convenience. If you want security then it's TouchID from 5 fingers + 8 digit pin + your first dogs girlfriend's name.
