Description
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.
Additionally, you can use Duo Mobile to manage two-factor authentication for other application and web services that make use of passcodes.
Duo Mobile also has a companion app for Wear OS, Duo Wear, making secure authentication even more convenient on your smartwatch.
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.
Additionally, we will request access to use your camera for the sole purpose of scanning QR codes when activating accounts. Accounts can be activated by other methods if you choose not to do so.

Least obtrusive, most efficient, and fastest 2FA (two-factor authentication) app I've used. I had my doubts, but since being REQUIRED to use it at GMU, I've grown to really appreciate this app. If you HAVE TO use 2FA, "Duo Mobile" is the way to go, if your institution supports it. Two thumbs up.

It works well. I would give it 5 stars but when it opens the keyboard, it opens to Alphabet instead of Numbers.

I was sent to Duo by Facebook in order to log on. Duo knows I have an account but won't allow me to log on or open the account to get a verification code from Facebook. As a result, it has locked me out of Facebook which I use for business.

I use for remote Work, and it wouldn't load to get the code to for me to work on my work Apps

It's easy to use but probably one of the most useless double security apps ever, I don't see why you would realistically need to use this app unless you want to make your life difficult, every time you log into something you will have to open this app on your phone assuming it is set up, and you will have to type in the 6-digit code and after so many hours even if it's your home computer you will have to do this again, so it's pretty much pointless

Backups were enabled on my phone and synced on my Google account. Restore is not working. I've lost multiple accounts access. I'm moving away from this app.
