Fingerprint Sensors Really Do Improve Security

A couple of weeks ago I wrote about a ProgrammableWeb article positing that biometric sensors decrease security. I made the case that unless you were a criminal with incriminating information on your phone, that was incorrect. I went on to speculate that it was most likely that the fingerprint sensors actually increased security because people who couldn’t be bothered to enter a 4-digit code to unlock their phones might find the the fingerprint sensor convenient enough to secure their phones.

That turns out to be true, at least for iPhones. The The Verge reports that Apple says that before TouchID about 50% of iPhone users locked their devices. After TouchID, that rose to nearly 90%. Actually, the whole article is interesting and worth a read if you have any interest in iPhone security.
