The passcode can’t die yet. The iPhone 5s’s Touch ID fingerprint security system can be unlocked with your finger even if you’re asleep. That means a jealous lover could hold your phone to your thumb while you slumber and read all your texts, call logs, emails, and more. Apple confirms that a dead thumb won’t work. Chloroforming the victim might, but international spies will have no luck cutting off a Prime Minister’s thumb to access their secure files / selfies. Apple also doesn’t send a copy of fingerprints back to its servers, and instead stores them in a “secure enclave” in its A7 processor designed to be inaccessible by hackers or other apps. TOuch IDApple worked hard to make the the Touch ID security system easy to use. So easy a 5s can be unlocked by a cat, your toe, or even your…member, if it’s registered with your phone. The real issue, though, is that Touch ID has no way of telling if someone is passed out.
