Duo Mobile

By Duo Security

This app is only available on the App Store for iOS devices.


Duo Mobile works with Duo Security's two-factor authentication service to make logins more secure. The application generates passcodes for login and can receive push notifications for easy, one-tap authentication on your iPhone, iPad, or Apple Watch.

Additionally, you can use Duo Mobile to manage two-factor authentication for other application and web services that make use of passcodes.

Note: For Duo accounts, Duo Mobile needs to be activated and linked to your account before it will work. You will receive an activation link as part of Duo's enrollment process. You may add third-party accounts at any time.

License agreements for third-party Open Source libraries used in Duo Mobile can be found at

- Added an exciting (and long-requested) Duo Restore feature that allows you to securely restore Duo accounts in-app!
- Duo Mobile now requires iOS 9 or later.

Customer Reviews

An App done right...

This app gets it right. Quick push notifications to the iphone that can be read with 3D Touch, making it a breeze to approve and deny requests.

The biggest plus though is the presence of the Apple Watch app that is fully functional and not just informational. Please don't take any of these features away in future updates!!

No more pop up?

With this new update, push notifications no longer pop up at the top of my screen and allow me to approve a login from there. My phone actually doesn't even tell me I pushed anything to my phone... I have to exit out of whatever app I'm in and open the Duo app manually to see that I have a push notification. User experience is absolutely awful.

Too Loud

Just used Duo with headphones in. Ridiculously loud, hurt my ears.

There is no reason for the app to make any sound at all, since I am already holding my phone when I use it.

Please allow push notifications to be muted or just remove the sound.
