  • No Cloud Backup Sep 26, 2021

    By jaumb830
    There are many reviews complaining that deleting the app, migrating to a new device, etc… lost access to their 2-factor auth codes. This is exactly what you want from a security perspective! That is precisely why I rated this app with 5 stars. Very few 2-factor apps do not backup to the cloud and this is one of them. No question that cloud backup is extremely convenient but there is often a trade-off between convenience and security and this is a great example of that. This app is for those who choose a bit of extra security (codes only stored on the device) over the convenience of having their codes stored both on the device and in the cloud.
  • Essential App, But No Cloud Backup Dec 3, 2020

    By Proteus846
    This is one of the most essential apps on my phone. I don’t know why I trust Google with my 2FA codes (I don’t really) but this is a very useful and important app. It is pretty basic as far as apps go, but it works for the intended purpose. They just added the ability to transfer 2FA codes when upgrading to a new phone. They released this feature less than a month after the second wave of new iPhones came out… so less than a month ago I did the transfer manually, turning 2FA off and back on for my new phone across a dozen services. Some were easy to transfer, others were the opposite. It took over an hour. Their timing with this feature is awful, but at least it’s here now I suppose.

    I wasn't going to review this as it's just and authenticator that I only need to use for a few seconds a day... But having just got a new phone I have to give praise to the ease of transferring from my old phone to a new one. You just have to create and scan 1 QR code and everything is instantly transferred. 👏👏👏 Credit where it's due to google. Now just add folders and icons and you'd really have the best app for this.

    A lot of morons don't seem to understand the purpose and functionality of 2FA. It's supposed to be tied with a phone that you are in possession of. If it breaks, you should've had a spot where you could store the recovery code. I'd be more than concerned if the authenticator is connected to my account, then it'd be a security nightmare. The app itself is great, and even works offline.
  • Finally!!!!! Dec 12, 2020

    I just wanted to say Thank you for finally putting a export accounts option to move from device to device cause this was always my more preferred app but due to lack of exporting accounts couldn’t take the risk so I’ve been using the Microsoft version. I did like how there was a Apple Watch version although It was never really that useful anyway. But I hope maybe there might be a Apple Watch version of this someday if not that’s fine then. Please always keep improving this app.

    Simple Layout. The only thing I don't like about this Authenticatior is that ALL of the code fonts are the same color, which leads to mistakes when punching in your code b/c your eyes overshot to the line above or below. If you could assign colors or have it so that every second line has a different color - I'd would've given it 5 stars.
  • Is this the update we’ve been waiting for? Dec 3, 2020

    By 2trot
    I saw with the most recent update Google added the feature to move accounts to a new device. Previously the Authenticator app only moved Google accounts so if it now moves all accounts that are stored in the Authenticator app that would make this app 100% more useful. I only change devices every few years so I’ll need to wait to confirm but this appears to be a major update with a feature that people have wanted for a very long time

    At first this app was a bit of an inconvenience when I couldn't find my phone or on the other side of the house and I didn't notice the small time ticker so a few times I entered a code that had changed while typing it - those were my mistakes not the app! This app provides a layer of security that has proven itself time and time again... Great and simple app!!
  • Won’t start after iOS 14.2 update, v3.1.0 of the app Dec 3, 2020

    By philiaagape
    (UPDATE: it’s working again after app update! The App Store told me there was no update available when I first checked, but now 10 min later there is an update. Problem was Apple, not Google.) I have loved google Authenticator for my 2fa needs: SSH verification and websites. But now the app will not start. I’ve rebooted my phone and checked the App Store for updates but I’m running version 3.1.0 of the app already.
  • It’s alright... but they listened to my feedback and improved! Dec 8, 2020

    By iLangston
    The app doesn’t explain many of its features well and has noticeably less features than the versions on other phones. I sent a detailed feedback message about important features that were missing, and a few weeks later all the features I mentioned were either improved upon or added! It makes me happy that my input was listened to!

    This app is useless if your phone is lost, breaks, etc. You're unable to sign into the app to pull up your account but no - if you're unable to see your QR code or or codes, you're unable to login. It really sucks. I had to get a new phone so I'm unable to use the authenticator to login to Facebook so I have to wait for them to review my driver's license. Don't use this app.
  • Terrible mfa application. The absolute worst. Sep 4, 2021

    By monster trucks and dogs
    Use any other MFA app, but this one. It does not save your information. If you change phones or migrate phone platforms, you are completely screwed unless you remove mfa from all your apps before you uninstall the Google Authenticator app. And if you lose your phone, you are just screwed with no recourse. If you use the Microsoft Authenticator, at least it will remember your information while you are on the same phone platform. But Google? Nope. Don’t even bother to ask for help because all you will receive is arrogant script kiddies belittling you for something you didn’t even know you were supposed to do. I’ll be uninstalling many Google apps in the coming month. I can definitely do without you at least Microsoft has support for the products they make. Imagine if GM made you ask other car owners how to use the windshield wipers, or how to change a tire. Google’s arrogance is amazing. I’ll make use of capitalism and find a better mouse trap.

    By uriaz castillo
    Don't use this app. literally any other authenticator would be better. WHY IS ITNOT LINKED TO MY GOOGLE ACCOUNT?! After replacing my broken phone, the app no longer shows any of the codes in the new phone. The only way to move them over to the new phone is by scanning the code from the old phone. What kind of bs is that?! Getting a new phone because your old one stopped working completely locks you out of any account that you've set up with this trash app.

    By Dan Nordmann
    Big fail going to a new device. It literally says 'go to your old device' with no other option to import the accounts from the old device. It's strange that somehow the Google Authenticator app doesn't associate the accounts with my Google account. I'll admit I don't know enough about authenticator apps to understand why this roadblock exists. What bothers me the most is that there wasn't another option if my old device was unavailable.
  • Do not use this app! Feb 3, 2021

    By Doggettall
    If you are in a situation where you are forced to use this app, be sure to keep backup codes so that you can access whatever applications you need to access in the event you lose your connection with Google authenticator. Because of a recent Facebook debacle and not knowing that it was necessary to save recovery codes with Google authenticator, I am now unable to access a 10+ year old Facebook account that includes some business connections. Facebook‘s issues are on them however, since I have a long-standing Google account, I don’t understand how I am unable to recover the connection with my Facebook account to allow me to get back in again. Is google authenticator completely unaffiliated with Google? Very disappointing and in 2021, I can’t believe things are this difficult for the average every day user.

    I hate it so much. I forgot to transfer this onto my new phone and now I can't access any account that requires this app to open it. I can't call help desk to cancel because they are only open during my work hours and the wait time is longer than my breaks and they are not open on the weekend! WORST APP EVER!!! If anyone knows an alternate solution please please help 😥😭
  • App Deleted ALL My Accounts - STAY AWAY Sep 29, 2021

    By MisterBigJake
    This app displayed duplicates for all my accounts. Naturally, I deleted all the duplicates. A few days later I was prompted with the “get started” screen, and to my horror ALL of my accounts were deleted(including crypto wallets and other extremely important things). As it turns out, I am not the only one affected. Simply search “Google Authenticator Duplicates iOS 15” online. I am currently locked out of ALOT of money and several productivity accounts at work and might be completely out of luck. I expected much better from Google and this has only hastened my separation from their products and services. This is inexcusable. Typically I am lenient, but when a product exists to secure your online accounts, it shouldn’t effectively lock you out of them. This is outrageous and it blows my mind that QA did not catch this.

    It is a bit aggravating that google still has not put a warning anywhere in the description of this app. Using it as verification for an account that your identity isn't tied to has a significant potential to result in permanently losing access to that account if your phone is lost, stolen, broken, etc. There is no way to recover the auth codes, despite it being a pretty simple task to allow people to back them up to their google account
  • DESERVES 0 STARS Sep 16, 2021

    By J0CCC
    Do not get this app!! I’m sure there are other apps that can safely store your information. I got my phone smashed and haven’t been able to retrieve anything, I thought everything saved to my iCloud but nothing was backed up. I had the screenshots from this app but due to have my phone smashed, I obviously can’t see them. I was never sent an email (as they should confirming this service) and have 0 trace of what I used to create this account. You’d think it’d work with a google account but no, it’s like I never had it. I’ve been unable to reach my passwords to accounts I’ve had for years and I have read every site possible with no solution. Google has no contact number to reach when you need help and if they do they just send you to the most unhelpful links. It’s a really unpleasant experience I urge you to not get this app.

    The appearance of the app should be improved. A recovery option should also be added when one changes devices due to force majeure. enable the option to be able to synchronize with the PC or with an extension in google chrome applying the aforementioned changes. If. Better access to the app with extra protection integrated into the types of security offered by the mobile.

    By MySaviorLives21
    Easy to use. Functional without significant software issues. This app would also be very handy to have a widget which was present when I swiped left on my iPhone so that I would not have to click into the app every time as my current organization requires two factor authentication every time I login.

    This app is awful for trying to get into your accounts again, if you change phones it requires you to go back to your old phone and transfer account over to your old phone. The problem with that is that most people don't have their old phones so how the hell are going to get your old Google authentication account back. Now I can't get into a 3rd party account that had for years. DO NOT DOWNLOAD THIS GARBAGE!
