    I find the app works fine, and very pleased compared to another apps I had to use. It always works; cellular, wifi or the deep basements. As far as switching the buttons, they were naturally backward anyway. It took some getting used to but I did. Face it, everything changes. Guess some people never had a PC, never used email, still have their original cell phone. Change is inevitable, no one likes it but we deal.

    Search/Sort Needed - In general the app works but could benefit from a sort and/or search feature. I currently have 36 accounted connected to Duo for 2FA. Trying to navigate through this list is tedious, especially since I can't put in custom account icons. Sorting alphabetically would be an improvement but the best option would be the ability to search by service, login, or both.
  • Duo Works Exactly As Intended May 12, 2022

    By TheManyen
    The app works fine, it provides 2 Factor authentication in a variety of ways. If a user has an issue with duo its not the app makers fault its their IT or security department implementing it poorly or not explaining how it works enough. Complain to them, don’t go after the manufacturer because it won’t improve your experience. There are options in Duo you yourself as a user can do to cut down on the amount of authentications like choosing to remember certain devices. You should also absolutely only use the Duo push feature or use a hardware token instead of phone calls. They are the most reliable and safe methods available. If you use these methods you should only take a few seconds to authenticate every time, and thats only a few times a day. I use Duo twice a day, in the morning and after lunch, and I’ve had maybe one issues with it over 6 months. It works people, you just need to be willing to learn.
  • The app works fine, it's on the users Oct 26, 2021

    By Snakestar
    I just want to say that my experience with Duo started out a tad rocky, but very quickly got better. I have gone through 2 phones, and helped my friend set up his new one and had no problems. The issues people are running into are that they're not setting up a secondary form of authentication. I use push notifications to authenticate, but when I replaced my phone, I just had duo call me to authenticate and I was in my accounts in seconds. I was then able to add my new phone to duo. If y'all just dig a little into the settings, you'll find everything you need. The company is giving you the tools for not only using your current device, but also very quickly adding new ones, even when your old one is out of commission. Use those tools, and you'll be fine. An authenticator app shouldn't be easy to bypass. That's the point of 2-factor authentication. Learn the app, and you’ll succeed
  • Works perfect BUT new users please read my advice: May 24, 2021

    By AppleUserSince2004
    This works perfectly fine to enable 2 factor authentication for school or business. However I’ve seen some upset user stories so I want to share this piece of advice: Compartmentalize Work, School, Personal authentication apps. Once you have duo downloaded it might be tempting to point your personal accounts to duo for convenience but remember your duo enterprise or uni account isn’t reliable for personal use as you are not the account owner. Microsoft, LastPass, Google just to name a few all have 2 factor apps. Download one of them and keep your personal life separate from business. To those that have “new phone” horror stories, I’d personally recommend an authenticator with cloud backup support. Such as Microsoft Authenticator. (Not affiliated with MSFT but their app works well for me.)

    Lets you back up your account and accounts linked. Perfect for when my phone breaks. I see a lot of the complaints mentioning the app doesn't show the notification, the app is set up to only run when open in the background. Unless you have opened it previously, you won't get notifications. Plus, you know when you're trying to log in anyway, just open the app and approve the request if the notification doesn't show...
  • Handles an annoying task with aplomb Jun 25, 2020

    By scoopster
    I hate the time required to perform two-factor authentication, and so was dreading when my institution began to require it. I was pleasantly surprised that the Duo app handles this task rapidly, much more so than any other app-based or text-based method I’ve used. Usually within about 2 seconds, I can approve a request with a single tap of my Apple Watch (the notification includes an “approve” button) or via two taps of my phone. I wouldn’t hesitate to switch to this system for any other account I use. EDIT: looking in another review, it appears that I could also be quickly approving with a single swipe or 3D-touch and tap from my phone. Perhaps a brief blurb instructing this within the app would be helpful because I would have been doing so all along!

    After reading the negative reviews, I’ve come to the conclusion that people seriously need to take a moment to understand HOW 2FA works, WHERE and WHAT the roles/responsibilities lie and are for each vendor (eg Coinbase vs Duo), and WHY 2FA is important. Is the app perfect? No. Does it work well for what it was designed to do? Yes. Can it be improved? Yes. Here is my wishlist to improve the usability of the app, hopefully the devs are reading! (1) I have well over 50 tokens (many from the same service), please introduce folders or a way to organize/group tokens. (2) Allow for custom icons instead of restricting it to just the ones you’ve decided to include; this would also help me find tokens more quickly. (3) Allow for token access from a widget on the lock screen (either display passcode or tap to immediately open the token in the app).

  • Honest Technical Review May 2, 2022

    By SBCelsius
    I think it is funny that overall the reviews of this product are complaining when there is clearly no technical experience from these users. Working in the technology field, a lot of these poor reviews could be resolved by reaching out to your school/workplace to ask for help from resources who have done the proper training on this specific 2FA. Also, googling will give you the majority of the answers on how to resolve these specific issues. The 2FA works as it should, and the more knowledge you have on the platform/technology, the better your experience will be. Have colleges/workplaces not provided proper training? I have so many questions for the people leaving negative reviews.

    U2F is a great idea but needs to be implemented with some key things in mind. A person is the ultimate and only true trusted entity. Duo very poorly handles the eventuality of a phone breaking, being lost, new numbers. This can be partially avoided for 90% of cases if people always set up 2 devices at the same time, more the better. 3 devices would fix 95% of complaints problems. However there needs to be a way to transfer to another phone after-the-fact, the technology allows, not the app.
  • Endless Cycle of frustration Aug 19, 2021

    By Lphilliieswc08
    The Duo Mobile app is realistically one of the largest stressors I have experienced in my life. Upon getting a new phone I was unable to access any of my school work/grades/tax information for months. If you need to get a new device it requires that you verify the new device with your old device, but for many people when a new device is purchased they no longer have access to their old device. Their “help” support staff is among one of the worst of its kind (which is saying something). It took me approximately 6 hours to recover my accounts. Moving on to normally logging in the process is arduous and frankly broken. I have no way to remove my old phone number as the primary verification. There is a “click to accept” box to remain logged in for 24 hours on the login page, although you must be verified to click the box, and upon verification you are immediately redirected away from the page. The system is inherently broken. Yes calling may be faster than scrolling through all your texts looking for old verification codes, but I should NOT have to receive a phone call or spend minutes searching my texts simply to do economics homework. If you are an administrator considering using this app, please find some other service. Using duo mobile will cause your employees/students immense stress and disdain against your organization.
  • Got a new phone, now I can't log onto my university account Apr 11, 2021

    By QueenBee2121212121
    This is the worst app I've ever used. Absolutely unnecessary and difficult. I've put up with it until now, but I can no longer sit silent. I recently got a new phone and in oder to reconnect duo to my university I need to log into my university account. But in order to log into my university account I need to verify it through duo. So obviously through this very dumb circle I can no longer log into my university account on my phone. Duo does offer verification though my old phone, but guess what? I no longer have that phone so it is absolutely impossible for me to verify my account through my old phone. I sincerely hope my university stops using this app as this is the worst experience I've ever had. All I want to do is be able to check my grades on my phone and I'll never be able to do that. And soon my 120 day access will run out on my labtop and I will no longer be able to access my school account which contains my grades, classroom, assignments, and more as I cannot verify my university account through duo. Making it virtually impossible to have access to my school account all because I got a new phone. This is the WORST app and experience I've ever had.

    Does not allow users to manually add codes, you have to use a qr code or select the service you need from a list. This would be fine if not for the fact that the reader app won't let you scan from files on the phone and the preset lists don't have what you need 99% of the time. Poorly thought out, use something else.

    This was a fine app. Not a great one, but good enough. Untill the developers made one off the most unreasonable change I have ever seen by swapping the location of approve and deny. I use this app about three times a day on average and two out of the three times I'll miss click deny. Beyond that about one out of five times I will go on to miss click yes on the suspicious login page. Please change it back or add an option to set the location of the button.
  • My school forced me to use this May 3, 2021

    By Rose Mulet's Biggest Fan
    No one cares about me enough to try to hack me. The much bigger risk is that I forget my password and lose access to my accounts! This is happened to me many times because of these stupid mandatory changes and is WAY WORSE HARMFUL than the risk of actually being hacked. These “security features” make simple services a PAIN. And they commonly LOCK YOU OUT OF YOUR OWN ACCOUNT. I changed my phone number recently, and this has caused me to get LOCKED OUT of many basic services that require these stupid “two factor authentication” YEARS worth of information GONE because of “Security” What a joke! Also, why should I trust YOU with m my information? Because I DON’T, and I should have the right to NOT give it to you! Many services now make me change my password and use special characters which means I’m much more likely to forget it, losing all of my information! Stop forcing people to use these. They don’t make you safer, they just make your life more annoying and more likely to lose your information due to you forgetting your needlessly complicated password. Listen to the people. I wish I could give you and companies like you 0 stars but I can’t

    This is the absolute worst authentication app out there. I have not been able to fill out my timecard for a month because of a problem with switching phones, and our schools IT faculty haven't been in at all to help get it figured out. The apps amazing at keeping people out, especially the owner of the account associated with it!! If you're going to study at uni buckle up because every time you wanna sign into anything ANYTHING you have to whip out your phone to authorize. Horrible terrible.
  • The App that Ruined Online Communication Jun 16, 2021

    By Stauffages
    Look, I admit that I am not an IT security expert, but I have had compromised emails that security technicians were able to secure in moments. On the other hand, Duo has greatly reduced my emailing efficiency for the sake of security I do not need. It seems that they do not actually make a profit by marketing to individuals, but to institutions that choose to invest without surveying their own workers (insert the name of most universities in the US). This app prevents you from doing basic things with your email account if you do not open and use their app. It is literally an app that is made solely to promote itself at the expense of its investors. If you can avoid it, do not download this app. If you have not choice but to download it, let it do its thing to frustrate you, then write a review and communicate with your employer/institution. From my perspective, this is a parasitic application that is blindly invested in by people who don’t fully understand (or need to understand) what it actually is or does. If I could put negative stars on my rating, I would. I hate this app with a passion and I hope that enough people will respond to it as I am now, soon.

    Used to be able to refresh to see if the app would send the verification request, newer updates don't allow for the refresh. It frustrates me having to close the app and then reopen it just to see if the request is sent. Not to mention the amount of times I fail authentication just because the request takes too long to send without any way of being able to refresh to see if it actually went through. Bringing back the refresh option would make it much faster and easier to use and verify my school login every time I want to log in.
  • Employees need some control Oct 22, 2020

    By indiindianarl
    *** Please read MORAL implications I am not writing to critique the app itself as I just downloaded the app. A small background, I work for a company who now require this specific app to be downloaded on our personal phones, or we will have "resigned" from the company. My immediate problem with the app is it gives all control to the company, including the control to direct the app to change my phone, and no ability to turn off the app while not at work. I feel if the app is being forced on employees by employers to save them money, it should be a "moral" obligation on the part of the developer to give the employee (owner of the phone) some control over the app and how it may function on the phone. But instead, that area is turn off to the employee and total control is granted to the employer. In my case there is no on/off toggle where the app could be shut down while not needed to perform work functions, and thus reducing the employer's ability to mis-use the app on your phone on your personal time. Please consider the MORAL obligation to allow the person who is being forced to use your app to have some control how it will be used on their own personal phones. Not everyone works for company that are completely trustworthy. Just because the company made the agreement with you, should not automatically eliminate all rights employee may have over their own personal property, nor give 100% control to the employer over a non-company own phone.

  • Almost perfect! Sep 20, 2020

    By BroHanzo
    I love the interface and how there is a variation of event based logins and OTP requests depending on what security factors are necessary for what apps and services. My wishlist of features mostly consists of needing a complication on my Apple Watch to easily access to the application, rather than needing to search or find in my App Library on the watch, as well as widget access on the iPhone and iPad for further quick access to each OTP passcode I need to type in, as they don't always send push notifications when there is a login attempt made. Other than that, I think the app has come a long way and is user friendly with security as its top priority which is what I would want for any service like this
  • A great option for 2FA May 23, 2019

    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...

    This is for the 9th October update. I stopped receiving the notification sounds. Digging in, I found the app's default settings was to use a built-in notification sound. Looks like that sound is missing in this update. I picked one of the Android notification sounds and all is good now. Looks like this particular release might not have been tested thoroughly before release. Over all the app has been pretty good. No delays in getting the notifications, or in the "approve" message being sent back to the server. Edit: I am on Android 9 Pie Edit 2: I now have the new version, 3.32.2, build 323206. The notification reverted back to "App provided sound" and still no audio notification. It does vibrate. Edit 3: Issue in edit 2 turned out to be my phone. Restarted it and all is good now. Changing app rating to 4 Stars (There's always room for improvement! 😉 )

    Search/Sort Needed - In general the app works but could benefit from a sort and/or search feature. I currently have 36 accounted connected to Duo for 2FA. Trying to navigate through this list is tedious, especially since I can't put in custom account icons. Sorting alphabetically would be an improvement but the best option would be the ability to search by service, login, or both.
  • Interface, interface Mar 23, 2020

    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.
  • Version 4.0.1 introduces bugs with push Oct 28, 2021

    By Polly Glossia
    I have been a happy Duo Mobile user for 5+ years, but the latest update brought with it some issues. First the good: I can access a fuller version of Duo on my Apple watch (5) and generate and OTP directly from the watch app. This is FANTASTIC. Now the gripe: I can feel the push notification on my watch, but when I raise it to approve, sometimes there’s nothing there, and when I look at my phone’s lock screen: also nothing. I have to open the app on my phone to approve. This is a small-ish inconvenience, but the bug is inconsistent (sometimes push works on the watch, sometimes it doesn’t, and I can’t divine a pattern yet), and for an app with one job, a small, introduced inconvenience is a relatively big deal. Looking forward to seeing this fixed!

    I feel the app for a few years and very much thought it was exactly what was needed. However, a recent update touted as an improvement to the app has been a big setback. Among the dumbest things they did was reverse the placement of buttons in the application, so that you no longer have the approve button in the same location. That also stops my watch from being able to approve requests without having to unlock the phone. It also needs greater screen space for your list of entries.

    This new update has been a step backwards. Up until now the app has been fine. Now I'm unable to Select/Change the pictures for the services. And don't get me started on switching the deny/approve buttons. I'm not usually one to jump on the "it looks different so I hate it" bandwagon that usually happens with updates but this really has been a major drop in both function and ease of use.

    Very annoying app. The worst part is that the push notifications just don't work. I have to manually open the app to see the request and approve it. Then, a few minutes later, the push for the original request will finally show up in my notifications, by which point it's useless and I don't need it anymore. Also, I emailed the support email for the app store to mention my issue and all they said to me was that the email support was for paying DUO users. Why put that email for the free app?!

    The new update adds unnecessary padding, animations, and clutter to the app that was not present before. Sure, some elements look "better" but a lot has been changed for the worse in the process. The switch of approve/dismiss buttons is absolutely maddening, messing with thousands of people's muscle memory. The switch also removes the ability to approve from a watch. If they change it back it'll be equally annoying as well, so not much winning here unfortunately.

    U2F is a great idea but needs to be implemented with some key things in mind. A person is the ultimate and only true trusted entity. Duo very poorly handles the eventuality of a phone breaking, being lost, new numbers. This can be partially avoided for 90% of cases if people always set up 2 devices at the same time, more the better. 3 devices would fix 95% of complaints problems. However there needs to be a way to transfer to another phone after-the-fact, the technology allows, not the app.
  • Endless Cycle of frustration Aug 19, 2021

    By Lphilliieswc08
    The Duo Mobile app is realistically one of the largest stressors I have experienced in my life. Upon getting a new phone I was unable to access any of my school work/grades/tax information for months. If you need to get a new device it requires that you verify the new device with your old device, but for many people when a new device is purchased they no longer have access to their old device. Their “help” support staff is among one of the worst of its kind (which is saying something). It took me approximately 6 hours to recover my accounts. Moving on to normally logging in the process is arduous and frankly broken. I have no way to remove my old phone number as the primary verification. There is a “click to accept” box to remain logged in for 24 hours on the login page, although you must be verified to click the box, and upon verification you are immediately redirected away from the page. The system is inherently broken. Yes calling may be faster than scrolling through all your texts looking for old verification codes, but I should NOT have to receive a phone call or spend minutes searching my texts simply to do economics homework. If you are an administrator considering using this app, please find some other service. Using duo mobile will cause your employees/students immense stress and disdain against your organization.
  • Got a new phone, now I can't log onto my university account Apr 11, 2021

    By QueenBee2121212121
    This is the worst app I've ever used. Absolutely unnecessary and difficult. I've put up with it until now, but I can no longer sit silent. I recently got a new phone and in oder to reconnect duo to my university I need to log into my university account. But in order to log into my university account I need to verify it through duo. So obviously through this very dumb circle I can no longer log into my university account on my phone. Duo does offer verification though my old phone, but guess what? I no longer have that phone so it is absolutely impossible for me to verify my account through my old phone. I sincerely hope my university stops using this app as this is the worst experience I've ever had. All I want to do is be able to check my grades on my phone and I'll never be able to do that. And soon my 120 day access will run out on my labtop and I will no longer be able to access my school account which contains my grades, classroom, assignments, and more as I cannot verify my university account through duo. Making it virtually impossible to have access to my school account all because I got a new phone. This is the WORST app and experience I've ever had.

    Does not allow users to manually add codes, you have to use a qr code or select the service you need from a list. This would be fine if not for the fact that the reader app won't let you scan from files on the phone and the preset lists don't have what you need 99% of the time. Poorly thought out, use something else.

    This was a fine app. Not a great one, but good enough. Untill the developers made one off the most unreasonable change I have ever seen by swapping the location of approve and deny. I use this app about three times a day on average and two out of the three times I'll miss click deny. Beyond that about one out of five times I will go on to miss click yes on the suspicious login page. Please change it back or add an option to set the location of the button.
  • My school forced me to use this May 3, 2021

    By Rose Mulet's Biggest Fan
    No one cares about me enough to try to hack me. The much bigger risk is that I forget my password and lose access to my accounts! This is happened to me many times because of these stupid mandatory changes and is WAY WORSE HARMFUL than the risk of actually being hacked. These “security features” make simple services a PAIN. And they commonly LOCK YOU OUT OF YOUR OWN ACCOUNT. I changed my phone number recently, and this has caused me to get LOCKED OUT of many basic services that require these stupid “two factor authentication” YEARS worth of information GONE because of “Security” What a joke! Also, why should I trust YOU with m my information? Because I DON’T, and I should have the right to NOT give it to you! Many services now make me change my password and use special characters which means I’m much more likely to forget it, losing all of my information! Stop forcing people to use these. They don’t make you safer, they just make your life more annoying and more likely to lose your information due to you forgetting your needlessly complicated password. Listen to the people. I wish I could give you and companies like you 0 stars but I can’t

    This is the absolute worst authentication app out there. I have not been able to fill out my timecard for a month because of a problem with switching phones, and our schools IT faculty haven't been in at all to help get it figured out. The apps amazing at keeping people out, especially the owner of the account associated with it!! If you're going to study at uni buckle up because every time you wanna sign into anything ANYTHING you have to whip out your phone to authorize. Horrible terrible.
  • The App that Ruined Online Communication Jun 16, 2021

    By Stauffages
    Look, I admit that I am not an IT security expert, but I have had compromised emails that security technicians were able to secure in moments. On the other hand, Duo has greatly reduced my emailing efficiency for the sake of security I do not need. It seems that they do not actually make a profit by marketing to individuals, but to institutions that choose to invest without surveying their own workers (insert the name of most universities in the US). This app prevents you from doing basic things with your email account if you do not open and use their app. It is literally an app that is made solely to promote itself at the expense of its investors. If you can avoid it, do not download this app. If you have not choice but to download it, let it do its thing to frustrate you, then write a review and communicate with your employer/institution. From my perspective, this is a parasitic application that is blindly invested in by people who don’t fully understand (or need to understand) what it actually is or does. If I could put negative stars on my rating, I would. I hate this app with a passion and I hope that enough people will respond to it as I am now, soon.

    Used to be able to refresh to see if the app would send the verification request, newer updates don't allow for the refresh. It frustrates me having to close the app and then reopen it just to see if the request is sent. Not to mention the amount of times I fail authentication just because the request takes too long to send without any way of being able to refresh to see if it actually went through. Bringing back the refresh option would make it much faster and easier to use and verify my school login every time I want to log in.
  • Employees need some control Oct 22, 2020

    By indiindianarl
    *** Please read MORAL implications I am not writing to critique the app itself as I just downloaded the app. A small background, I work for a company who now require this specific app to be downloaded on our personal phones, or we will have "resigned" from the company. My immediate problem with the app is it gives all control to the company, including the control to direct the app to change my phone, and no ability to turn off the app while not at work. I feel if the app is being forced on employees by employers to save them money, it should be a "moral" obligation on the part of the developer to give the employee (owner of the phone) some control over the app and how it may function on the phone. But instead, that area is turn off to the employee and total control is granted to the employer. In my case there is no on/off toggle where the app could be shut down while not needed to perform work functions, and thus reducing the employer's ability to mis-use the app on your phone on your personal time. Please consider the MORAL obligation to allow the person who is being forced to use your app to have some control how it will be used on their own personal phones. Not everyone works for company that are completely trustworthy. Just because the company made the agreement with you, should not automatically eliminate all rights employee may have over their own personal property, nor give 100% control to the employer over a non-company own phone.
