I'm not worried about some spies targeting me. I'm worried about something like Samsung where you can hold up a picture of a person on another phone and it accepts that! Any idiot can hack that, and that's what I'm worried about. I'm not saying Touch ID is absolutely secure, I'm saying it's secure enough that regular people don't have to worry about it. Samsung's solution isn't, so I was just hoping they've made some massive improvements so it's secure enough for most people. What I'd really like to see most is two factor biological authentication, with Touch ID under the display in addition to an iris scan.
