Duo Mobile

By Duo Security

Open iTunes to buy and download apps.


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.

What's New in Version 3.9.3

- Fixed a crash on launch for some users.
- Fixed an issue where requests would incorrectly report they were expired.
- Updated EULA for international compliance and to reflect third-party OATH-compliant token support.

Lost configuration after restore

Just upgraded my phone via an encrypted iTunes backup & restore and Duo lost all my configuration information, however, Google Authenticator did not. Now I have to carry two devices until I get that sorted out. What a crappy user experience Duo!

It would also be nice to be able to have a push dialogue that takes a single touch to approve similiar to the Apple ID 2FA dialogue box. Please work on that!

Watch app doesn't work

I'm not sure which end it the problem, ios9 or the watch os2, but the watch app doesn't function anymore. The key shows up, but clicking on it does nothing until the app is opened from the phone, which defeats the purpose of even having the watch app...

After iOS 9 update, editing and reordering wrecks havoc

After updating to iOS 9, when I edit my list of tokens to better organize my items, there are now duplicates!
