    Overall this app does what it says it does, the reason I am giving it 3 stars is because it will not allow me to approve logins from my Galaxy Watch4, however my coworker who has an iPhone and Apple Watch can approve logins directly from her watch. This seems like a crucial feature that Wear OS users should also be able to use.
  • 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.)
  • 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!
  • Misplaced blame Aug 12, 2020

    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).
  • 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.
  • 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...
  • 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

    Not bad. Definitely not as good as some of the other 2FA apps out there but it works. I see a lot of people complaining about adding new devices but I was able to pretty easily. Four stars because the Google Drive restore doesn't work.
  • Love it - but Apple Watch app seems to have a bug Jul 31, 2019

    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!

    Works great, except for on wearable. Used to be able to approve duo prompts on Galaxy Watch4, and now I cannot. The app will allow to show notification, then it will not show approve or decline.

    Have to refresh the code to get a code that works. If I try to use the push function, it times out, unless I manually refresh the code. What good is receiving a push or a code if I have to go in first and refresh what automatically comes up? Also, our infrastructure team has submitted a "help desk ticket" for these issues. They're closed out without resolution and no one ever reaches out to try to resolve the issue. The latest ticket has been open for nearly a month.
  • 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.

    This is the absolute worst app I have ever had the displeasure of using . My company forces us to use it. 90% of the time it is never working or locks you out and the tech support simply says " I don't know what to tell you" They never follow up with issues, outright lie to you to get you off the phone. Issues never get resolved . Horrible horrible app.
  • 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.

    The reactivation process is straight out of Kafka's The Trial and The Castle. I am requested to provide a password which I use to access a third-party site. Duo Mobile does not name the site; and it declines my password for the 3d party that I used with Duo Mobile.
  • 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
  • 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.

    Useless. Required to use for Canvas at my college, as the only way around having to have a code texted to me at every login. But, everytime I log in and attempt to add my devise permanently, and scan the QR code, I am told the operation failed because of no internet connection. Well, there is both a wifi and mobile connection, so that's not true. Just a dead end, absolutely worthless app.

    DUO MOBILE, fix the problem. You guessed it, I am here because I got a new phone and the app will not reconnect now to my new phone so I can't receive the push notifications and therefore am locked out of my LEARN account. I cannot get back into my old phone because it's dead and gone. You should be allowed to/able to pair again with a new phone and confirm via a text/phone call. This is outrageous. PLEASE FIX IT! School is tomorrow!
  • 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.

  • Love it - but Apple Watch app seems to have a bug Jul 31, 2019

    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!
  • New standard Sep 12, 2020

    By Latentreview
    2FA seems to be the new standard as far as consumer security is concerned. At first I was a bit frustrated with the inconvenience of having to use my password and phone to log on to my university account, but the added security is definitely worth it. There so many malicious actors when it comes to attacking university data and this switch to Duo Mobile is for the better. Couple of tips: remember to keep one time passcodes on hand, and allow third party accounts to reconnect automatically (for when you reset your phone or get a new iPhone). Definitely recommend this app not just for school accounts, but any other account you want to add extra security to.

    By Brianna Coleman
    Edit: I was able to restore my lost accounts fairly easily once I redownloaded the app. I found the help article which helped a lot. I recently (2 days ago) got a new phone with the same number, and as soon as I downloaded the app, it connected to all the accounts connected to my same number. Super easy to restore and transfer as long as you have the same number.
  • Ignore the negative reviews May 12, 2021

    By SourdoughJosh
    Duo provides a really great 2fA experience, far better than most I’ve dealt with to date. The push notifications are generally fast, and having Apple Watch notification approvals is a fantastic time saver. Virtually *all* of the negative reviews appear to be folks who, frankly, are completely clueless about how 2fA works or what it’s for. The fact that simply copying Duo to a new, unauthenticated device doesn’t immediately provide access to your work accounts is a *PRO*, not a con — it means the Authenticator is doing its job to prevent unauthorized logins! Thank you for writing a quality 2fA app that is stable, robust, and easy to use.
  • Nice and easy Sep 3, 2020

    By Graspingcard56
    Pretty straightforward and works to a T. Anyone who wrote a 1 star review are just people who create problems for themselves. Get this, one guy says it was duos problem because his child and him weren’t able to effectively communicate when to use the 2 factor authentication. Another guy, said it was such an inconvenience that the accept and decline buttons were placed at the bottom of the screen. Like it’s 2 factor authentication, why does it matter that the button position isn't in the optimal space? It literally takes 2 seconds to do this but apparently it’s such a hassle. Nice and easy process
  • Misplaced blame Aug 12, 2020

    By Stuball80
    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).

  • Reliable two factor authentication Aug 5, 2020

    By Spartanickel
    We've used DUO for several years for two factor authentication. It's secure and reliable. It definitely gets the job done. The app isn't too bad, but could use a little more polish. Namely, I wish the buttons fir approving or disproving a log on attempt were positioned a little higher and made a touch smaller in the app to make one hand use easier. The buttons are large, going to the screens edge. I have accidentally hit the button before when picking up my phone where the palm of my hand touched the edge of the screen in just such a way that it registered as a click granting approval. Luckily, it was me trying to log in.

  • 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.

    Works great, except for on wearable. Used to be able to approve duo prompts on Galaxy Watch4, and now I cannot. The app will allow to show notification, then it will not show approve or decline.

    So I used duo mobile for my Instagram and what ended up happening I forgot my password and when I went to my duo mobile app it had my account disabled because I had received a new phone and when I was trying to login on a computer it took me a second to realize I never made an account on my computer so when I did my device wasn’t on the account I had just created and I wasn’t able to get into my Instagram account at all. Luckily I still had my possession of my old phone that I used and was able to get into my account again just a heads up duo mobile I hope you have this specific problem fixed of when you receive a new phone other then this story it’s a good app

    Even after updating it most of time I never receive notifications directly to approve it , at time the approval is delayed by then the authentication is timed out and slows down my work as well! I have to open the app for every login and then wait for the the approval which again depends if I get it on time or not. It is time consuming !!
  • Very Difficult Sep 26, 2019

    At first the app was going well for me, but then i got a new phone and the app didn’t transfer over so i had to redownload Duo but the thing was, the app wasn’t connected to my apps (Snapchat and Instagram) anymore but my apps still required the codes. So i tried going on Duo and clicking “Looking to recover your accounts?” at the bottom of the screen and it was frozen, as in you weren’t able to click it but everything else worked. So i looked up a solution on safari and nothing came up that would solve my problem except for Androids and i have an iPhone. So i’m currently permanently logged out of Instagram.

    Have to refresh the code to get a code that works. If I try to use the push function, it times out, unless I manually refresh the code. What good is receiving a push or a code if I have to go in first and refresh what automatically comes up? Also, our infrastructure team has submitted a "help desk ticket" for these issues. They're closed out without resolution and no one ever reaches out to try to resolve the issue. The latest ticket has been open for nearly a month.
  • Endless Cycle of frustration Aug 19, 2021

    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.

    This is the absolute worst app I have ever had the displeasure of using . My company forces us to use it. 90% of the time it is never working or locks you out and the tech support simply says " I don't know what to tell you" They never follow up with issues, outright lie to you to get you off the phone. Issues never get resolved . Horrible horrible app.
  • 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.

    The reactivation process is straight out of Kafka's The Trial and The Castle. I am requested to provide a password which I use to access a third-party site. Duo Mobile does not name the site; and it declines my password for the 3d party that I used with Duo Mobile.
  • 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
  • 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.

    Useless. Required to use for Canvas at my college, as the only way around having to have a code texted to me at every login. But, everytime I log in and attempt to add my devise permanently, and scan the QR code, I am told the operation failed because of no internet connection. Well, there is both a wifi and mobile connection, so that's not true. Just a dead end, absolutely worthless app.

    DUO MOBILE, fix the problem. You guessed it, I am here because I got a new phone and the app will not reconnect now to my new phone so I can't receive the push notifications and therefore am locked out of my LEARN account. I cannot get back into my old phone because it's dead and gone. You should be allowed to/able to pair again with a new phone and confirm via a text/phone call. This is outrageous. PLEASE FIX IT! School is tomorrow!
  • 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.
