When Apple first introduced Touch ID last year, its functionality was somewhat limited to the extent that it only allowed users to unlock their device and authorize App Store purchases. With iOS 8, Apple is taking Touch ID functionality just a tad further.
During today's WWDC keynote, Apple's Craig Federighi announced that iOS 8 will enable third-party apps to use Touch ID for authentication purposes. This should be a welcome feature for users keen on keeping certain apps free from prying eyes, whether it be Tinder, Mint, or Facebook.
Apple's iOS 8 website reads in part:
For the first time, you'll have the option of using Touch ID to sign in to third-party apps - there's no need to enter a password. Your fingerprint data is protected and is never accessed by iOS or other apps.
