Google Authenticator App

Google Authenticator works with 2-Step Verification for your Google Account to provide an additional layer of security when signing in. With 2-Step Verification, signing into your account will require both your password and a verification code you can generate with this app. Once configured, you can get verification codes without the need for a network or cellular connection. Features include: - Automatic setup via QR code - Support for multiple accounts - Support for time-based and counter-based code generation To use Google Authenticator, you need to enable 2-Step Verification on your Google Account.

Google Authenticator app reviews

  • Broken 1/5

    By bobofromNY
    The codes this app generates do not work anymore after I changed my phone. Completely useless. Reinstalling it did not help either. I can't believe this piece of junk came from Google.
  • Lost all my data 1/5

    By pbrand559
    The app worked one day and then the next it was like I had never used it. Lost all of my keys and created massive headaches. I am still trying to regain access to multiple accounts. Garbage. DO NOT DOWNLOAD.
  • 2step is a joke 1/5

    By Queen Vicki xo
    Agree with all 1 star reviews. Why must you lose access to other apps when you purchase a new phone?! Wasting so much time!
  • Seriously! Google should be embarrassed 1/5

    By Rajtriv
    Fix this or lose tons of customer support . This is horrendous
  • Switch phones. 1/5

    By Justgothroughforthelove
    I dare you.
  • Awful 1/5

    By AstrophysicsOfNASA
    Straight up terrible, lost my gaijin war thunder account that i used to grind
  • No way to transfer to new phone 2/5

    By John Graybosch
    If you get a new phone there's no way to transfer the codes. It won't even re-display the QR codes for you to scan with your new phone, not to mention some kind of backup for your codes. It kinda basically does the job, but it's a little klunky anyway.
  • Can't sign in? 1/5

    By Ryannicknamenottaken
    Why isn't there any sort of backup feature? You guys are an embarrassingly uninnovative bunch. Aren't you like... the richest company in the world or something? How about some R&D funding? Clowns. No update since Feb2016? SMH!
  • Worst app ever 1/5

    By Aalllylka
    I was trying to get back into a very important email account that we lost the password to, and when I got it wrong it told me to use this app. The app was absolutely un helpful and did nothing for me. Would definitely not recommend.
  • Do NOT Use This!!!! 1/5

    By Techric
    The ONLY situations you should use this is for is ONLY for Google's services. Otherwise DO NO EVER USE this app. Why? Because if you ever lose your phone, do a hard reset, or just lose the app, ALL of your tokens will be gone F-O-R-E-V-E-R! That's right. The app doesn't save the tokens that you set up for 3rd-Party emails, bank accounts, etc. You WILL BE SCREWED!
  • Not user friendly compared to its android version 1/5

    By sks@123
  • Once a fast app, no longer. 1/5

    By OneNOnlySev
    Used by other programs I run, I had to use this app. Before, it wasn't a problem. Now it's *MANDATORY* to set up 2-step verification on your Google account before you can even use the app at all; which is both completely useless to me and, for most, stupidly hard to find. If I had something important on my Google account maybe I'd do this myself. But I use a Google account as a connection account, it has nothing valuable on it. Immense waste of time, and the update forced me to re-setup every app that used Authenticators prior, which I had to first DISABLE to redo. In short, huge waste of time, ludicrously pointless fluff, thank you for making a perfectly streamlined app a pain in the rear.
  • I need help retrieving old Authentications 1/5

    By Albino Yeknom
    I need to retrieving the authentications I had, back before I removed this app I have a few on there, since then I've accidentally deleted the app. I thought I would be able to get my stuff back since it had the Cloud symbols when I went back to download it but NO. ALL GONE, with no way to retrieve now I can't access account๐Ÿ˜ž PLEASE HELP!
  • It lost my codes... 1/5

    By Gillianne Yarber
    Don't trust this to keep your codes.
  • Authy is sooo much better 1/5

    By Wings13
  • Wish we could search among 100s codes 3/5

    By Jimmy Costanza
    No search, very basic app but does the job.
  • Doesn't scale well 1/5

    By Art Carney
    If you have more that 6 or so codes it will start doubling them in the list, and the UI gets disabled somehow so you can't delete them without restarting the app. Really wish it used native UI instead of the Google stuff. Out of place and probably the source of the above problems.
  • No token backup, use Google's new button Prompt. 2/5

    By RDEinMichigan
    Used this easy great app for years without issues... Until one day my phone accidently got drowned in water. Days later I got a new phone and my iCloud backup worked perfectly, all but the Authenticator app lost all my tokens. This.was a good app who's time has past. Use Google's new "Google Print" instead, which simply uses the iPhone finger print button, no codes to copy/paste or enter. Google's new solution is faster, easier and more secure.
  • Pretty easy app to use 4/5

    By MrRedstonePro
    My only complaint is what is the point of the space between the numbers when that is not what you right
  • No wonder its 2 and a half star 1/5

    By BankerJake
    Does not work at all. All the codes provided is invalid. What is this app for if the codes are not working.
  • Useless 1/5

    By Th1sNam31sTak3n
    This app never works.
  • If you format your phone, you lose all your codes! 1/5

    By Lalaperson12
    I am moving to another app.
  • Zero Star if possible 1/5

    By Lezah57
    Terrible! I lost my Android smartphone with the Authenticator app and had no way to transfer access codes to my new iPhone. Never going back to this app. I switched to Authy.
  • Doesn't work with O365 accounts 3/5

    By Drumpat01
    Works well for everything besides a Microsoft Office 365 account
  • Absolutely terrible. 1/5

    By HNS3
    I used it to set up a bank account and literally tried to use it the next day and it has not generated one correct code. I lost all my money online because of this app.
  • You'll Be Sorry If You Get A New Phone ๐Ÿ˜ฑ 1/5

    By Annonomous
    I had to get a new iPhone because my old one became defective. Trying to recover my old key codes was impossible. I am in a world of hurt and can't be made whole again using this app. This is terrible! You have got to find a way to make this portable between devices. Maybe consider storing some information in the cloud.
  • CDCf 5/5

    By dfbchn
  • Stable and solid, needs a watch app 4/5

    By herocero
    6 stars if I can get codes on my watch instead of needing to search for my phone. Otherwise it's solid and stable, I don't seem to have reset and lost account info like other reviewers here have experienced.
  • Simple, works well... until you have to move to a new device 1/5

    By Zseba
    Google, seriously, what are you thinking? If you want people to use this app for more than just the gmail account, just build a back up option. I have been used your app just fine and i changed devices with iCloud back up and restore and it was fine. Now Apple support advised me to do clean restore and I wanted to back up and restore the Authenticator app separately... good luck with that! I had to manually switch all my accounts to LastPass authenticator which does have a built in back up option.
  • Buggggg 3/5

    By Alex Chulito
    Hey there's a bug when you add a new authentication with a bar code. You get two children but the problem with my purpose is to be able to make sure that you have a good day.
  • I like it a lot 5/5

    By AznagYo
    Pretty easy to use, I recommend to safeguard your email content
  • You won't be able to log-in to any site forever if you lose your iPhone. 1/5

    By ์—์˜ค๋‹ˆ
    I back up my iPhone to iTunes. Today I tried to restore my backup into a new iPhone, and I discovered that all the tokens are gone in new device. If I erased my old device, I just won't be able to log-in to any site forever. Don't use this app if you don't want to lose your account at some unexpected point.
  • All codes are lost if you change phones 1/5

    By Telebyte
    An application for two-factor authentication must be 100% reliable. This simply isn't because if you change phones, all your access codes are lost. In my case, this locked me out of a 6 digit Coinbase account. Coinbase is so backed up with customer service on this issue it took over two weeks for them to recover my account.
  • The App Works Great! 5/5

    By anilagrawal
    I don't know why there is low ratings for this app. I have been using for a few years now on both android and iOS devices and it's been working perfectly. No clue what problems other people are facing with this app and why/how.
  • Easier than texts 5/5

    By MeganMH
    I haven't had problems with the app. It does exactly what it says: gives you a code instead of text. I thought it wouldn't be that much more convenient but was worth trying. Ended up being a lot easier than texts, especially because you can just copy/paste codes instead of remembering them and typing them.
  • Extremely frustrating to find QR or Passcode 1/5

    By Siksek
    Changed my IPhone and now this app has become worthless!! Setting up is extremely frustrating and quite difficult all ups that work with 2FA are now screwed and rendered unable to login to - thnx Google!!!!!!! Removing this worthless app!!
  • does what it says it'll do 5/5

    By Ashleybmeyer
    This app does exactly what it has set out to do, which is participate in security theater. This futile piece of cruft will serve as your ally for the 5 minutes between when you install it, scan the barcode your bank tells you is necessary for your security, and then delete off your phone.
  • Wow thanks google... 1/5

    By Elmer101023
    I lost my Ubisoft account because of this google says 2 step verification is disabled but Ubisoft keeps asking for 2 step verification I have no way of getting my codes to login into my Ubisoft account because I can't set up a 2 step verification on my google account because it keeps asking for a phone number I DONT HAVE A PHONE NUMBER SO WHAT AM I SUPPOSED TO DO NOW??? I lost all my games because of you ALL THIS HAPPENED JUST BECAUSE I GOT A NEW PHONE WHY CANY MY ACCOUNT JUST RECOGNIZE THAT I JUST GOT A NEW PHONE WITHOUT HAVING TO USE A STUPID PHONE NUMBER
  • Need password protect or fingerprint 1/5

    By socaliguy34
    This app never requires authentication to open it. If someone got into my phone they could get into this app very easily to get the authentication codes. There should be settings to add a password to use itouch to secure it with my fingerprint so ONLY myself can get in it. Thanks
  • Needs to be brought up a notch 1/5

    By iNexxFear
    Microsoft authenticator outlines google here. I like how Microsoft allows approvals when you hit their authentication spots. Google I guess can do it but you need to install their google app? Really I don't need no "ok google" tool on my phone for an authenticator application to notify me. They need to include that. And yes when you do get a new phone it does require re-setup. Needs to be a lot easier. Again Microsoft does just that .. re-approve your device and then things come into alignment Sad. Google is usually so phenomenal
  • What is this?!! 1/5

    By Meadowbrook8*
    I used it once and I can't access my account any longer! This application is garbage!
  • Needs the ability to edit account names 3/5

    By Adam Woodworth
    If you have a bunch of accounts in this app you better hope the addresses displayed are meaningful. There is no ability to edit the description of an account, which would let you easily remember which is which.
  • Good 5/5

  • Buggy 2/5

    By pGlau
    Every time I scan a code, it enters it twice. Also gets stuck on a screen where it only shows existing codes, but does not allow editing or deleting. Only way out is to hard-exit the App and restart it.
  • Great 5/5

    By Carter2579643
  • Google Authenticator 1/5

    By CupcakeFyte
    The App is CRAP! There's no instructions whatsoever for setting up. Based on other review, I'm not going to bother with a setup.
  • It works 5/5

    By ThomasPhillips3
    It does what it's supposed to do. Syncing between devices is directly against the point of this app lol. I switch main phones regularly (between Android and iOS), and setting up all the MFA accounts is just a part of that. Scanning the barcode makes it as painless as possible though. I like it.
  • Does not update through iTunes! 1/5

    By Blue-H3
    After running updates on computer with iTunes, you still have to manually update all Google crap from each mobile device. This means iPhone, iPad & iPod Touch all have to be done separately. That wastes my time!!
  • Save your code seeds! 5/5

    By jemenake
    For security reasons, this app doesn't back up the seed/starting codes you use when you add a new service to the Authenticator. For this reason, make sure that you PRINT the QR code from the page you're scanning (Dropbox, Google, Coinbase, etc) and save that printout in a safe place. You will need these printouts to restore your services to Authenticator when you transfer to a new phone.
  • Doesn't work after updating to new iPhone 1/5

    By eclisastewart
    It worked fine until I upgraded to a new iPhone. Now it's asking weird questions that I don't know how to answer. I deleted the app to download it again -same weird questions. Rule #1: don't make your customers feel stupid. They ignored that rule. Now I'm off to find a replacement. ๐Ÿ˜–
