Am I the only one to notice this?
"...so it is rare that...two separate fingerprints are alike enough to register as a match for Touch ID. The probability of this happening is 1 in 50,000 for one enrolled finger. This is much better than the 1 in 10,000 odds of guessing a typical 4-digit passcode...the 1 in 50,000 probability means it requires trying up to 50,000 different fingerprints until potentially finding a random match. But Touch ID only allows five unsuccessful fingerprint match attempts before you must enter your passcode..."
So Touch ID odds are 50,000 while passcode is only 10,000. But since you only have five attempts for Touch ID to switch back to passcode, The Touch ID security only adds 5 odds to the previous passcode system and we end up with 10,005 odds of some successfully breaking into your phone.
A whole system to gain 5 odds of breaking into the phone. Brilliant.

- onedognight 13y agoHow is it that banks, who arguably store more value, get away with 4 digit ATM codes? They do the same thing Apple does with Thouch ID. They lock you after a small numer of failed attempts falling back to a secondary form of authentication.
- code_duck 13y agoYou have a certain number of tries with the passcode, too. You need to process that number in the same way. Also, the slick, futuristic appeal of fingerprint access goes a long way to achieve Apple's branding goals, which surely is just as important to selling iPhones as actual security.
