How does it Work?


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 https://www.duosecurity.com/legal/open-source-licenses.

  • Interface, interface


    By Angry-Johnnie
    As far as working as a 2fac this app is fine, it does that. The issue with it is that it’s a really simple app but has an annoying interface. If the buttons for the push notification could be moved to a more thumb friendly location that would be great. It’s just a screen with 2 buttons, there’s no reason to make me adjust my grip on the phone so I can reach the accept button. I should be able to pick the phone up and hit the button in one motion. Not pick the phone up fumble with the position in my hand then hit the button. It’s annoying and unnecessary. The whole screen is there to use for this purpose and is empty. The buttons are large but the phone screen is also large and it puts the buttons out of comfortable reach for one hand use. Stack them in the middle or something. Maybe a flick gesture, or both, I dunno.
  • A great option for 2FA


    By mnkjrdgyrgh
    Seeing all the low ratings based on a business’ or university’s decision to apply additional security to their networks, I had to add my two cents. It is 2FA, not Duo, about which most are railing. If you don’t like 2FA, rid the world of hackers and thieves that will use every available means to get into any network they can. Until you accomplish that, accept the fact that for those trying to secure a network, 2FA is a necessary precaution, much like a deadbolt on a door. And Duo is a good method for applying 2FA. We primarily use Duo Push for accessing our systems and it works very well. Unrelated note: Duo works much better than this rating system, which will tell you after the fact that a nickname has been used but won’t suggest one that hasn’t been...
  • Love it - but Apple Watch app seems to have a bug


    By icewalker90
    Edit - issue seems to have been fixed. Also, leaving the Duo app running in the background on the phone, which I hadn’t been doing before, helps. I implemented the free tier of Duo to safeguard my personal VPN against unauthorized access. It works great and having an Apple Watch app is neat too. But recently, I noticed that my watch app wouldn’t generate passcodes anymore. Push notifications to the Watch still work. Restarting the watch seems to work once and then it won’t give codes anymore. I couldn’t find a way to send feedback in the app itself, so I decided to leave a review. Hope this minor bug can be ironed out so I can get back to enjoying that extra convenience!
  • One of the most convenient 2 factor authentication apps


    By Mr.Millian
    We were told to use this app for 2 factor authentication by my university. I checked the reviews and saw a lot of very poor reviews and kind of went “oh no.” These reviews as far as I can tell now are mostly just people who were also required to use the app, and had never used two factor authentication before. The app has been bug free for me and has the most convenient approach I have seen. They are complaining about two factor authentication as a system and being required to use it, not how well the app functions.
  • Thanks to this program, I’m locked out of my Coinbase account


    By kwasi5179
    Losing money fast! Downloaded this program to put another layer of security on my cryptocurrency account (Coinbase) on my iPhone 6S. I do NOT use iCloud. It was working fine, then later I decided I didn’t want it, so I deleted it thinking it would also delete the two-way authentication. I could still log in to Coinbase for several about 6 months after, and even updated CoinBase from time to time - never having to put in a key from Duo Mobile (since I deleted the app anyway, I thought it wiped out two-way authentication). Suddenly, to my surprise, IT NOW REQUIRES A KEY FROM DUO MOBILE!!! So I re-downloaded this app thinking I’ll just simply redo two-way authentication I get from this app. NOPE!! Now I HAVE NO IDEA HOW TO RECOVER my Coinbase app, no help to Duo Mobile. LOSING THOUSANDS OF DOLLARS BECAUSE OF THIS APP!!!!
  • I would pay to not have to use this


    By TXMOM04
    Daughter’s university recently implemented usage of Duo. If I need to log in to pay something, I have to wait for her to get the approval. The problem is, we are in different time zones. So she may be asleep when I need to access her account. It is extremely frustrating, and there should be a way to have two different devices authorized for approval. At times when we are together, there can be a lag when she gets the actual notification. As others have mentioned, if you don’t see the notification pop up you can easily miss it as it doesn’t stay on the screen. Please make an option for two devices...it would also be helpful for when you get a new phone and still have access to authentication on the second device.
  • Simple and intuitive


    By run7xc
    So many reviews panning these guys for stuff that isn’t their fault... The Duo app is the best 2FA app I’ve used. Adding new accounts is a breeze, and the hold-to-copy function makes entering passcodes a piece of cake. Additionally, certain accounts can use push notifications for authentication. I use Duo to secure several accounts and it works exactly as it should. I guess I’d have to say don’t set up 2FA if you don’t know what it is. All the bad reviews I’ve seen are from people who don’t understand 2FA and really shouldn’t be reflecting on this app.
  • Could be better


    By Yours truly_a
    I recently started having to use this for school and it’s a major inconvenience, but that isn’t all the developers’ fault. I really think they should add some kind of “trusted device” feature that would allow users to have one computer that you wouldn’t have to go through two-factor authentication every single time, but maybe just the first of every month. It’s annoying not being able to check my grades quickly or look at an assignment quickly on my own computer. I hate that I have to use this but the developers could make the experience less painful
  • Review that actually covers the APP...


    By fplsl
    Got a decent laugh reading these 1-star reviews. The following apply to almost all of them: -Mad at Duo because they didn’t retain recovery key for Instagram -Mad at Duo because the company using their service failed to educate their own people properly -Mad at Duo for “making” them use 2FA Sad my actual review and 5 star won’t make a dent in those 1 star ratings. Here’s the truth for actual paying customers who may read reviews. This app does what it’s built to do, with a high accuracy rate. Any user having issues with the app I’ve seen so far falls under two categories; not reading setup instructions or false expectations of how it should work. App pushes fast. Offline login methods work. Tech support is very responsive. Customer success is their focus. I don’t work for Duo, just felt a well developed app deserves a fair shake for any non-teen that may be reading.
  • Don’t believe the naysayers


    By PensionFund
    If you read the negative reviews, you’ll see people are complaining about two-factor authentication (2FA) in general. Yeah, it is an inconvenience. The advantage is increased security. Most of these people should be complaining with their IT departments or any service that requires it. Unfortunately, Duo is what they see when inconvenienced and this blame Duo. If you ever had to use a different 2FA provider, then you would realize that Duo Security is leagues better than anything else out there.
