Two-factor authentication for the OneDrive app on Windows 10 Mobile
You can use the Lumia 950’s Iris Scanner to unlock the app
Microsoft has added an additional level of security to OneDrive mobile. Thanks to build-in support for Windows Hello authentication, people with Lumia 950 & 950 XL phones can now unlock the app by using the Iris scanner.
To enable the feature: go to Settings → Additional device sign-up → On
In order to turn the feature on, you need to enable sign-in to your device and turn on Windows Hello → Go to Settings → Accounts → Sign-in options. Next time you open OneDrive you will need to scan your iris and hit OK.
Tip: You can select ‘Never’ in the ‘Require sign-in’ menu, so Windows Hello will only scan your iris when you open the OneDrive app.
With Windows 10, Microsoft allows app developers to secure user data through two-stage authentication methods – using Windows Hello or Microsoft Passport. Windows Hello currently supports fingerprints, facial recognition, and iris scanning.
