Microsoft on Tuesday updated OneNote for iOS and OS X with useful new features, including fingerprint based Touch ID authentication to unlock password protected sections of your notebooks.
There's also a new Storage Provider extension in iOS 8 which let you easily add files to your notebooks from your favorite cloud storage service like, say, Dropbox.
On the iPhone, OneNote finally allows you to move and rearrange your notes anywhere you like. Moreover, the note-taking app has now gained ability to open notebooks stored on SharePoint Servers.
OneNote for the iPhone, iPad and Mac apps are free downloads.
