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

Version 3.28.0

The Duo Mobile app now enables you to securely restore your third-party accounts (such as Instagram, Amazon, etc.) after you get a new device or reset your current device. This does not affect Duo-protected accounts managed by your organization.
Note that you must opt-in to third-party restore and set a recovery password to use this feature.

Works with Apple Watch

This is an excellent App.

I leave it open in the background on my iphone x and have duo in my dock on my apple watch s3 and generate codes without having to pickup my phone, which is great.

I wouldn't use another 2FA app.
