Besides new user features such as health tracking, user interface optimizations, and improved messaging, iOS 8 introduces several new APIs for developers that will result in improved App Store apps that tie even deeper into the system. Two of the most notable API additions in iOS 8 are Touch ID and Extensions. The Touch ID feature will allow developers to design applications that can use the iPhone 5s’s fingerprint scanner, and Extensions will allow them to integrate their own software into share sheets within other apps.
1Password, a popular password management program, is testing an updated version of its iPhone, iPad, and iPod touch application that taps into both of these APIs. We’ve gone hands-on with the beta version—which developer AgileBits stresses is still a pre-release build with functionality and interface elements that can and will change—and both features feel right at home in a third-party app. You can find tours of both the Touch ID and Extensions features below:
