I love this app. It is great and easy to use but it has one major flaw. You can't back up the security tokens. I can understand why as if you can back them up someone can steal them. That said some places don't seem to present recovery codes when enabling 2fa and if you lose your phone before digging into the sites setting page to grab them it is too late. I would really prefer some form of secure backup to say your google drive or something so that the accounts can be synced across devices or recovered in some way.

Overall great app, I used to love it ... until I got a new phone and discovered there is no way to actually move all your saved Authenticator accounts to your new device. You have to re-link them one by one. Great way to keep customers who keep buying Android phones! Moving to Authy for authentication ... the app is not as great, but lets you keep backups.

Migration option removed Authenticator used to have a 'migrate to new phone' option, so if you had to change phones, you could easily take all the 2fa accounts to the new one. Piece of cake. Now that option was quietly removed in early 2016, with no explanation. Now you can do it by removing and re-adding all the accounts one by one. Madness. Avoid.

It's a great app, but only problem is it does not synchronized applications that you have installed through bar code for easy retrieval. Once you loose the company app code you have a hard time retrieving it especially when you need the code also to gain access to the account on the third-party website and no proper support is provided to disable two-way authentication. example: I can't access my teamviewer anymore because I reinstalled google authenticator and it's asking for code which I can't get on the site without providing security code from Google authenticator. Would be great to have an authenticator that remembers the apps scanned and retrieve it once you provide your google account credentials.

I can't get back all the accounts I associated with my authenticator app after I lost my phone and got a new one... Very bad... Now all those accounts are locked because I can't do the 2 step verification... Please do something and I will give five star... App has been awesome till I met this challenge

Rubbish. If you have to reinstall authenticator, you have to either scan a barcode or enter a provided key. Where is the barcode? Where is the provided key? Extremely tedious and useless. Too much effort. You need to reconsider how someone can add an account without such a cumbersome and difficult process.

Too easy to not do it I'd heard of MFA (multi-factor authentication) but hadn't done it yet - a recent leak made me quickly reconsider. Setting up 2FA via your Google Account is a breeze - Google's made this a brainless, painless process to protect your information. And the Authenticator app makes the process of signing into your account(s) even easier. It doesn't get any better than this.

Great app for 2-steps authentication. My only complaint is that you cannot order the list. I would like to hide the ones for games I no longer play but still want to make sure the account is secure when I do return to the account a year later. Better yet, let us favourite the ones we use more frequently to show up on top of the list first.

Ok for day to day... but remember to DISABLE IT BEFORE YOU MOVE DEVICE. I Lost all my android settings after the last android update as it reset my device. No way of getting the codes to log in. Can only verify by text when skipping the initial login, but then settings don't sync ie ringtones, alarms, backgrounds all gone. Also all third party authenticator accounts need to be recreated when you move device.

It is a fantastic app, the recent visual update is lovely and clear. I would love the one addition of a pin code to actually access the codes. As in to make it really secure, when you load the app it will have the option to ask for a password/pin just to make sure no one can nick your phone to get the codes. Then again if they can see your texts that kinda negates that... aight ignore me and stuff lol

Let's say I have 2 devices, device A and device B. Currently, for the same account, the Authenticator app only allows one device to have the codes. But what if that device gets stolen while unlocked? The person would be able to use the Authenticator app on your device and gain access to your accounts. Please add a feature to easily have Authenticator work on different devices other than the one it's installed on.

Functionally great, could look better Really happy you can reorder accounts - I've been wanting this forever. Also great you don't need a separate barcode app to scan QR codes. What happened to the UI though? I agree with the many other reviews saying the same thing - too much wasted space by far!

Listen your users. Accept constructive criticism. Lets make GA THE best app for 2FA. You are already late... GA should be 2FA 👑 (the best app for twofactor auth.) -1.) Add fingerprint sensor auth. Easier than codes. 2.) Support "Tap to approve" (great feature!) for ALL, not just Google services. Poput/tap is lifesaver! 3. Enable backup & restore, but not only for EXISTING phone (what if lost?), but for ANY new device - protected with passwd for instance. and, 4.) Windows version of GA is a must. More availability on deskop, please. Bring significant progess! 💚

Backup problem. People think that the 2 factor authentication codes are linked to the Google account so when you sign in from another device all the 2 factor codes appear but that's not the case. One needs to be rooted to make a backup with titanium backup and restore to the new Android device in order to get the 2 factor codes on a new smart phone or tablet. I hope Google is working on a better way to move the codes to a new device. One can lock the app with an app locker application to prevent people from seeing the code

Worthless They demand to use a security key or barcode scan not a password like they used to. Google has to have your phone number, and be able to track you at all times or you can't use their stuff. My work already requires me to use Google so I have to use Google so have to let them track me. Unbelievably invasive and unnecessary. Big business privatizing our information for everyone else to buy. I have lost respect for Google.

Good, but missing key features I don't like that I can't change the order of accounts. I have dozens of accounts and finding my most used accounts is unnecessarily difficult. Ability to rename accounts completely would help, but the app only lets you change part of the name. Also there is no secure export/import feature, so every phone upgrade is a nightmare. Even from a Nexus 6 to a Pixel I was forced to regenerate dozens of codes on dozens of sites.

Not only does the interface suck, but what I can't wrap my head around is why it doesn't prompt with a notification when a login is attempted. I should NOT have to manually open the app. Also, I should be able to secure the app with a code or fingerprint. Using this with LastPass is horrible compared to the actual LastPass Authenticator app. The only reason I tried is you can only use one device with LastPass Authenticator.

I like it as if gives me another way to use 2 step verification on many of my accounts letting me sign in without the need of my phone being online and without the need for me to get texts. However it seems that it isn't working correctly with my Facebook account for some reason it shows it should work but when I try it, I get "invaild code" when they match. Overall though works with all the other apps and sites I use so 4 stars, 5 when Facebook works with it.

Now 5* after update Edit: with the option of dark mode, Google Authenticator goes back to five stars. Thanks for listening, developers! (Previous comment - "Got to agree with other commenters - the white background in the latest update is not good. Far too bright - if I want to use my screen as a lamp, then I'll do it with the profile screen I have set up for that purpose. Bring back the black background, if only as an option.")

Really angry at this. So my phone needed to be reset. It was crashing every two seconds. I reset it. I imagined since it was a Google App that my accounts and authenticator was syncing to Google so if I reinstalled everything would be there including the programs I was using 2-step for. I reinstalled and all is gone and a couple of programs I used cannot be recovered and are asking me to create a new account. This is upsetting. Going back to 2-step with phone. Find that to be superior since if I lose my phone I will still be able to recover my account by transferring the number.

Won't give code. Stupid thing won't give me code to log into uplay, also hat to remove from phones as it updated and now won't work at all. Had to turn 2 step of google acc as it wouldn't give me a code. Wants me to scan a barcode or or enter a provider key. Like WTF! Where are my verification codes gone? This used to work now nothing. And i can't log some things now cos of it.

Great app, but... Latest update knocked out my saved accounts. Only just realized it because I have my main computer as a trusted one for Google, and the game I use it for I have set to ask me to authenticate once a month. Now I have to disable 2-step and re enable.

I cannot open this app on a Google Pixel XL. It says I need to have a barcode or key. This may be since barcodes were added, since I see that was a check-in a few months ago that may be when this first became a problem. But now I have a new phone, so it could be that, too. Not sure. It used to work fine on a Samsung Galaxy S5. Cannot use this app until this problem is fixed.

The app has now twice lost my saved information when it updated. This has gotten me locked out of the sites I was using this for, with substantial hardship getting access to my accounts again. It doesn't seem to synch this information, so when it updates everything is lost. I do not recommend using this app. I'm going to find a different one.

It is so hard to link your account. Where do i get the QR code. Even if i get it i would have to be near a computer to scan it with my phone. You should atleast be more user friendly and tell us how do we set it up. Wasted like 20 mins in front of my computer wondering where i find the qr code. Pathetic!!

According to the app, I have the wrong code in because my time is off; but my time is right on the dot. Because of this I can't sign into one of my emails, so I was forced to make a new one. Thanks Google authenticator for, no reason, poping up and saying I can't sign in because I need to enter this code I didn't even know about.

This app has cost me a lot. I got the shock of my life when I gave my phone to my kid brother and got myself a brand new phone. I did a factory reset on the old phone and when I tried to reinstall my backed up apps, I found out that accounts in the GA has gone missing. Until Google do something about it, this app is as good as trash

Updated version have resolved many issues and added me features 😃 Wow! UI los and feel so good. Simple yet powerful enough & dark theme is my fav. Finally Google had listened to our voices and upgraded the app 😋

Keep getting invalid code I use this for work and it always takes multiple times to log in and last night it took me about 20 minutes to log on, and I work for a time sensitive company. I had late cases and a mess when I finally got back on! I had reinstalled the app, and unverified and reverified my phone and still took forever to verify the phone it kept saying invalid code. I've found if I enter the code right before it expires or a second after it works but I don't understand why, and of course, I'm the only one it happen to.

Lot of padding, white spaces and lot of wasted space in the last version (material design). This is very inefficient and adds a lot of scroll. Can you please reduce a bit and have a bit more information displayed on screen?

Feeling very disappointed When i reinstall the applications all accounts codes are removed and I'm not able to login anywhere. Add option to create an authenticator account to signin or the application recognize the device and start showing the codes of previous added accounts. And also add pin at startup.

Did Google drop support for this? Where is the Move to a different device in authenticator? From what I saw it used to be there, but is not there any longer. I have a bunch of other applications/sites/etc that use 2FA that I have loaded in GA, but there is no way to move it from my old phone to my new phone. The Google support document "Using a new phone to receive 2-Step Verification codes" references "In the section for the Google Authenticator app, click Move to a different phone." which is missing. Change phone only adds Google, leaving all the other accounts on my old phone (and what if I didn't have my old phone?). Moving to a different phone including all of the other 2FA entries was there in the past but unfortunately no longer. Useless....

I had an HTC sensation 4g and a Motorola cliq and this so worked flawlessly. Now I'm on the Sony xperia z1s and the app crashes all the time plus the codes generated doesn't work. Please fix so i could give this a 5 star rating once again.

Terrible! So I just signed up and you expect me to already know these codes? How about not making the average person jump through hoops. Forget about buying bitcoin online

We need cross platform backup! Imagine if my phone gets stolen/lost/damaged and I have to re-do all the procedure from scratch. This option is a must have these days. The app works flawlessly, but we really need the backup option.

This has been a great find since the day I was told about it! I've used to secure many accounts of mine which has paid dividends! Nothing like being at work and you get a notification of another login which failed because they don't have this app! I love it and use it where I can to keep my accounts secure!

I accidentally deleted one of my accounts on this app. I am now struggling with getting the codes inorder to login. Can someone please help me on how i can recover the account so that i will be able to login. I am going crazy right now as i cant access my account

It works when you need it to work. However when you need to move every account you authenticated to a new phone you'll soon find out that the functionality to do so has been removed for whatever reason. Creating a massive hassle since you will have to authenticate your new device and disable each authenticator individually. Put non-essential accounts on this authenticator if you absolutely need it, and use another app for the important stuff.

It's good up until the moment your phone breaks, then everything's screwed. I encourage everyone to set proper recovery questions and try to find your email account set up date and record it somewhere just in case, but on the fly this app is useful

Excellent I use gauth to provide 2FA for ssh logins, su/sudo attempts, Gmail, aws... and I also use it for work. It's practical security done, seemingly, very well. My only complaint is a UI problem. I have a lot of keys and the existing display options have no company option. It's frustrating to scroll through the list, especially when we could easily have a font size option as well as compact themes to reduce whitespace.
