The advent of TouchID is making it easier than ever to trust other people to use your phone without worrying if they're snooping through your files. Dropbox for iOS has been updated for iOS 8 users to support TouchID unlocking. With the service set up, launching the app requests a fingerprint scan before you get access to your files.
The update also brings support for the iPhone 6 and 6 Plus, allowing users with those devices to utilize every inch of their larger displays. In addition to those upgrades, the app has fixed a bug that caused problems when previewing RTF files in iOS 8. You can find the latest version of Dropbox right now for free in the iTunes store.
