Identity, security, privacy
Apple’s TouchID has taken the world by storm and, with official fingerprint biometric support now also coming to Android M, it looks like username and password prompts on mobile applications will soon go the way of the VCR and the gramophone player.
Still, unlike usernames and passwords, which we can change at will, we only have one set of biometric prints. If our biometrics fall into the hands of hackers, they become useless to us, forever. The consensus amongst industry experts such as the FIDO Alliance and Apple is that we must limit exposure to our private biometric data by not sharing it, keeping it instead locked down on our personal devices. In other words, that record of your fingerprint used to unlock your iPhone should never leave your device. Not even Apple has access to it.
