I used this app for my facebook account and one day my phone got formatted due to some issues...and this app also got deleted,now i'm not able to receive my facebook login codes and also can not access my facebook account PS:- how can i contact direct support services..is there any contact mail or contact number?

Forced to use it. I do not need this kind of stupid apps.

Pls I can't open my account on Facebook. I format my phone then i download this to get my code then the code is showing i open my Facebook acc and put the code its invalid I need your help thank you

Really cool!! We're using DUO for everything and it's very easy to administrate, congrats, this solved so much issues on my job

Could not get started

If I could rate this app a zero, I would. It has worked on my previous devices, but I can't even get it to download on my Galaxy s10. And I need this app to get into my computer at work.

Not getting installed

I restarted my phone and I can now longer get my account back

Forever locked out of my Instagram accounts with no help from Duo OR Instagram

Awful app. Forced to install and use it by my school

wow great thank you because of this app I can't log in into my ig account anymore since the codes simply stopped working

Nice app

I got locked out of my st.lawrence account bc the app updated and I lost my code

Good luck recovering accounts after resetting your phone or getting a new phone.



Good app

My account is gone due to use of this aap


Very nice

After factori reset my phone i can not start au duo app becouse i did not do back up. And a can not use fb app because i need code. And after i unistall duo it still need code



Great app

Aweful app. Use google authenticator

U hav to do too much work....!!!!

I changed my phone and for some reason it's not allowing me to log in, telling me by code is incorrect. This has been happening all morning a end very frustrating

i love u

Works fine for me. I am just amused that a ton of the one star reviews are from people who are complaining about having to use 2FA in general.

I like the app when I had it on my other phone but for this phone if the video keeps freezing in the screen keeps going black

I lost my mobile on 27th September. I bought new one and when I installed this app on new phone then the codes are not working. I am not able to login in my Facebook profile. Please help

I had problems!

Awesome product. I use it all over on all my devices. Only wish they had an app so you can approve requests on the Samsung Watch.


Lost my account because of the flawed system

worst app on the market don't waste your time search for another app immediately

Seriously? Not Android 10? USELESS security warning, since an android 10 release is not been released by the device vendor. Otherwise the option is to root and update or toss the device and replace, which I am am absolutely sure Duo will not fund. This is just the type of useless warnings that make people ignore otherwise good security practices. (Edit:) Duo's response is not helpful. Do not rell me my device needs to be fixed if it is OK. We SHOULD fix security issues that exist, NEVER ignore.

I only use it because my work makes me. The constant message of not being on the latest Android is infuriating.


Hello please help me I did a mobile restore my ID is no longer log in My due mobile account is not login any facebook account is not login annther cod is not receved Please helf me



It is bad to say that Android iOS 9 is not secure. it is very bad to show it as a security risk and blocking push services Update 1: No custom notification or anything. It just pure vanilla installation as given by our organization. But then yesterday I noticed it did not give me push notification instead it showed me the security warning. Update 2: Following the previous response I reinstalled Duo again. Though it gives the security warning but push notifications are working again. Thanks

My college makes me use this stupid app and that's dumb.


Great Application. Works as intended. Stop giving bad reviews because you have to use this to keep your account secure. Its not Duo's fault you give away your password, which was probably your first name anyway.


Hello Mister Due My Facebook Account is Not log in no received code my Mobile is restore & again not login my Facebook account please help me

Annoying at best

This is similar to Google and Microsoft authenticator. It has to much personal information inside it

Worst app ever. Terrible experiences with this app. I'm forced to use this app for my school account. Like what are the hackers gonna do? My homework. I'd give 0 stars if that were an option.

The app could use a sprinkling of visual polish, but there's no lag or wait time - just unlock your phone and tap "approve"! As for visual polish, 99% of the app looks great. However, the in-app Approve and Deny buttons look a little cheap, and that's the only part I see 99% of the time I use the app.


Make mind intel

Good and functional. I had to use this app daily for a couple years with school, and now have to use it occasionally for work. The app works well and looks nice too. My only compaint is regarding the feature that looks for security issues with your phone. I got a warning saying that I should update my phone because it isn't on the latest software. This would be useful for iOS, but not for Android. While Android 10 is out and I have 9, I can't get 10 yet for my S10+. This warning should either be removed, or updated to check on a device by device basis to see what the latest software is for that phone, rather than Android as a whole


It was good at first but then i tried to sign into my intsagram but every passcode keep getting decilne

The most difficult app ever. I don't receive push notifications and it doesn't recognize my email as admin which is strange because I only have two emails. Tried both. Been locked out of my Instagram for two days. Shouldn't be this hard. Beyond frustrated and there is no support number to call, just a bunch of links.

Doesnt give you a code

Being forced by work to use a third party app that wants accede to my photo and data usage is wrong.

Extremely useful

For the last few weeks, possibly since the last update, Duo doesn't respond to notifications. I have to open it whenever I send a push. It's not that big a deal now that I understand that's the case. I've tried the fixes on the site but nothing's helped. It worked fine for a couple of years before that.

Hello duo mobile I need your help my Facebook account recovery code is not working please help me

Can't update the device, because it has no update... This is not a security issue because you can't update! Jesus.

Works like a charm. Does exactly what is says. Clean interface with no frills. If you need an easy to set up 2-factor authentication system definitely give this a try.

Would give it 5 stars happily if it would let me approve 2nd factor from the galaxy watch...

I like it it was very easy to access

Remember this device feature does not work. You will have to reauthenticate every time.

Invasive sofware on my personal device so I can be allowed to do my job. Might as well have no privacy ever.

I was forced to install this app to enroll. Why not just enroll me with my mobile number?

I upgraded my phone and there seemed to be no way to regain access. Very frustrating. The option in the app to restore one's account did not work. Finally, by Google searching, I found a school website which gave the steps needed. This should not be so hard.

The worst security program ever. It takes forever to download. If companies knew how bad this is they would switch to anything else. Again avoid this at any means necessary. I'm using verizon home wifi and it fails to download. Just a terribel app.

Will not let me log in university site from phone to do work. I have full coverage yet I'm getting a message saying I need coverage. This has been happening for weeks.

Nothing like security by obscurity and vendor lock in. I cannot say enough bad things about this service and the experience of using it. I'm furious that my organization has allowed itself to be swindled into using it.

Used to work reliably, now frequently fails, have to open up the application to confirm, no notification ever appears.


Before I post, I need Duo to give me a security push

should be a law against compulsory installation by employer on personal device

This is required for my work and I have to scan a bar code but even though I am connected to the internet it says no internet connection so can't link workday to it

I was able to use this app until a few weeks ago when stopped working. I tried to reinstall it but it says that my device is not compatible with it. I have a Motorola XT1096. Thanks

Does this work even when my phone is OFFLINE? (not connected to any wireless network and/or mobile data is off?) 5 stars for now due to the ease of use for first time users like myself.


30+ presses in a day when using a cloud database (Snowflake). Every Odbc/jdbc database connection is a f***ing push request with four+ actions on the phone. To Duo: There is no option that is within my control to enable 'remembering devices' and the admins tell me it's not an option in Snowflake. I repeat, this is CANCER FOR PRODUCTIVITY! If you want to hobble your own workforce, implement this system!

The best MFA product in the biz.


App worked fine before the most recent update. I'm no longer getting push notifications. I've turned off push and turned it back on to try and reset it with no dice. Not the end of the world, but it worked once before so I'm not sure what happened. Update following support: While already in app, when my email sends the auth request to Duo, the app crashes on my phone. The push notification when I'm outside of the app is still not working. After push, open app, that's always worked.

Well designed

Trash, required by the stupid university it department

It pops up a notification asking if it can record audio and video to use...why would you need that if this is truly a non-invasive, data-collection app for people's PERSONAL DEVICES.

Use to, but no longer supports Android 9! Even phones released earlier this year (like my AT&T Galaxy S10 Plus) run Android 9. Mine won't potentially get 10 until 2/2020 at the earliest!

Occasional delays in receiving authentication prompts, despite good Internet connectivity. Excellently engaged product team still not convincing enough to make me update in the face of insufficiently detailed release notes. 😃 (Because Android apps can't be rolled back without using 3rd-party app stores, I don't update them unless there's a documented security vulnerability or show-stopper bug.)

Works smooth and quite fast

So again.. I have android 9 and 10 was released only for Google devices like a pixel deviceals... I have a Samsung S10 and in Canada updates are controlled by the carrier... Please actually look into it Then tie it to the carrier as well

One of the required apps for my workplace, there's absolutely no reason this app needs access to so much of anyone's phone to send them a 2fa pass code. I assume they're selling the scraped data? Uninstalled and went with a "manually call my phone" option instead because this app is absolutely ridiculous.

My College just started forcing us to use this app. It should be an optional service. Instead, now I need my phone to get onto anything school related. Like I need protection for my school stuff. Is someone really gonna log into my account and look at my syllabus or something?

I have lost my phone after that I am Unable to login my user id and I am also unable to find my account in backup

I like Duo Mobile. I don't like apps that decide to add themselves to my home screen when they get an update.

Thanks for slowing down my workflow against my will. I really needed that...
