App Extensions, Third-Party Touch ID Access Demoed With iOS 8 1Password Beta
With the update, 1Password beta testers are now able to use Touch ID to unlock the app's main password, which then allows the app to supply passwords directly to Safari using extensions. The entire process has been demoed in a two Vine videos from Gabriel Nevado (via MacGeneration), who accesses his 1Password content using Touch ID and is then able to enter a password from the app directly in Safari using the Share sheet.

Accessing 1Password on an iOS device with iOS 7 requires users to enter a master password each time the app is opened, and while the app has a built-in browser, it is not possible for the app to input passwords in Safari automatically. With iOS 8's new APIs, apps like 1Password are able to provide a much simpler user experience.
Earlier this month, MacStories shared an in-depth look at app extensions, which allow third-party apps to share services with other apps. The feature also lets developers create widgets for the Notification Center and it allows for custom system-wide keyboards for the first time. Touch ID integration for third-party developers is also one of the 4,000 new APIs Apple introduced with iOS 8.
The iOS 8 1Password update is only available to beta testers at the current point in time, but will likely be released to the public following the official launch of iOS 8, which is expected this fall.
