Comments on Duo Mobile for Android

★★★★☆ Ross Troha · Apr 7, 2026

One less star because of a minor usability thing which would make life easier for those us who need to type in codes into the app. The keyboard does not open up to the numpad or keyboard + number row at the top when clicking on Enter Code from a notification. Instead, it opens to the default keyboard without the numbers requiring Pressing+Holding or manually switching to the keypad. Otherwise, it works well. I don't have issues receiving the appropriate notifications, either.

I've always used Duo Mobile as my go-to two-factor authentication app for all my accounts, and it fulfills its purpose perfectly. It's a highly reliable tool that does exactly what it needs to do, while being completely free and refreshingly ad-free. The only improvement I would suggest is adding a wider variety of icons for the different apps and services we link inside, as it would make visual identification much easier. Overall, it's an excellent and secure tool.

I really like using it. Easy to use and easy to pick up travel quotes for when you travel. The pronunciations are helpful as well.

The qr code to add an account doesn't work and the rest of this app is still dog shit

★☆☆☆☆ Ame Mpano · Apr 19, 2026

The app just locks you out of your accounts when u got a new phone. I am now locked out of my account because it"couldn't find any accounts".it could have an automatic backup for accounts ... truly frustrated

Now, the duo isn't working. He said I need to update my Duo apps. When I check the Play Store, there is no update. A few weeks later, I found out my Android phone was too old to run the apps, so I bought a new one. I log in using my old email. Now, even worse: all my account access is disabled. I click on reconnect, but nothing happens. Please Update your apps, so I can log in using my old phone. Because it's still sending push notification every time I try to log in

Hard to use. Clicking the notification does not open the app to approve. Just goes to phone home screen, have to launch app manually, several clicks to find notification and approve. This is BASIC functionality. Why make it that hard to do?
