iOS 8 allows Touch ID to be accessed by third-party apps
One of the coolest features of the iPhone 5s is its Touch ID fingerprint sensor. It can be used as an intuitive and easy to use replacement for your lock screen PIN or iTunes password. Third party iOS app, however, can't take advantage of the sensor, which is a bit of a bummer. Well, this all changes with iOS 8.
Apple's iOS 8 lets third-party applications read fingerprint data via Touch ID. This would allow fingerprint-based login to be implemented into apps as an alternative the standard username and password. We have a feeling that developers of iOS apps requiring payment authorizations will be interested in the feature. Safety shouldn't be a concern as the user's fingerprint data will be stored safely inside the device's chip.
