  • How do you remove an entry? Oct 3, 2019

    By jollyturns
    How do I remove an entry?!! The edit button at the top right shows me a selectable list, but none of the items in the list can be selected. This is on iOS 13.1.1. It looks like a typical Google app. The original developers likely went to another team, since there no glory in working on an app after it’s been released. If you want to be promoted you have to show leadership, which is not in maintaining an existing app. It’s really sad, since a lot of people rely on this little app to secure their accounts. Including people that work at Google!

    Google's is the only Authenticator I've used, so I can't really compare and review. But in the past three or four years of usage, it's been a hassle-free and smooth experience. The app also doubles as Google's hardware based 2FA acceptor (unsure if that's how it even works), and I thought that was interesting enough to key in here.

    Google! You need to make this process simple when we purchase new devices ---- there is not enough information available to easily guide users how to transfer accounts to new devices.... however the process can be done in seconds once you have the know how. The problem I experienced is my authenticator app on my old device was not updated, hence there was no transfer accounts in the menu option..... once I updated, the export and import was easy as!

    I have read too many stories about people losing their devices and subsequently access to their two-factor authentication. In an attempt to be a responsible digital user, I was attempting to store my QR code in the event of an accident. Easiest way for me to do that is to screenshot the exported QR code, print it off, and store it in a secure location. I'm not able to do that due to security restrictions. Would you consider enabling screenshot ability in the app?

    If you have someone using your platform with your account on. I'd recommend downloading this app and turn on 2-Step Verification to your account to prevent them from getting inside your account. But here's an important thing, losing this app while you have 2-Step Verification on your accounts will lock you out forever. So it's recommended to setup up another security method to get into your account if you lose this app.

    Like many of the other 1 star reviews for this app - I am unable to restore my tokens after doing a factory reset on my phone. Not all auth apps are like this. Authy saved my tokens and any sites for that app are fine. Anything that was linked to my Google Authenticator, I am trying to regain access to. I know Google isn't the greatest when it comes to technology but you would think someone would have thought of this.

  • Locked out of exchange Acct Nov 10, 2019

    By disenfranchised driver
    Ive been using Google’s Authenticator for a while with no problem to access my exchange website account. Then I had to get my phone restored. Little did I know my saved codes were also gone too. Now I’m trying to log into my exchange site account, but lo and behold my codes don’t show in the authenticator. At first I was extremely furious at the exchange site for having this cost of massive inconvenience for the sake of security. Then I realized it’s probably this app that should’ve warned us ahead of time that after a factory reset, all our codes will be gone. For the laymen user, we don’t have the time to read the fine print and learn about stuff like this, and if it’s very important it should be easily told to us. So I’m locked out of my Account for days, but hopefully my account won’t be gone forever. Never trusting this app again, and may try out that Authy app to see if it’s any better. Very frustrating...

  • Very very hard to move phones. Will lock you out of all accounts Feb 1, 2017

    By samrecord
    Authy is sooooo much easier to use. This app used to be easier to transfer to new devices and setup in 2012. Sometime since then and now (2/1/17), it's become incredibly complicated to set up and use. After app updates on my iPhone I had to re-setup some of my google accounts that required this Authenticator. My apps obviously required me to use Authenticator. But then my Authenticator also required me to use my google accounts! A bit frustrating but workable, right? Just log into my google account sign in and security settings on my laptop to setup my Authenticator first, right? WRONG. It's stupidly difficult to navigate through the labyrinthine security settings pages in google to find the passcodes or the QR image that I need to setup Authenticator on my phone. I couldn't find it. I even googled on how to find it and couldn't find the answers. This is multiple layers of Google fail. So I just gave up. Switched off 2-factor sign in and deleted this useless app, much to my disappointment and security downsides. Google really needs to simplify all the crazy complexity and cognitive bloat they are creating in their ecosystem of stuff. Their "material" UI design looks nice superficially but is in fact very poor UX - It's just all labyrinthine. Nothing is "obvious" and intuitive.

  • Works but no frills Jan 6, 2018

    By Inetsuperman
    I normally don’t write reviews but since I use this app a lot for MFA it is not useful for multiple AWS accounts because you can’t change the name of an entry after scanning the barcode... you are stuck with the name the barcode gives you and if that account is AWS then it’s extra difficult. When you have several AWS entries where the only distinguishing thing is a 10-14 digit number that is not visible on the web login screen... once you set up multiple accounts you’re kinda stuck trying all of the TOTP numbers until one works because the names are not distinguishable and not editable upon creation. A simple edit to the account name is all I ask for. If that gets added I’ll change my rating. For now, it causes me enough extra frustration that I’m spending valuable time writing this.

    (1/5 DO NOT USE THIS AUTHENTICATOR) With an authenticator app being developed by the likes of Google, you would think that maybe they would have an app like this in the bag. And it is! (sort of) This authenticator does exactly what you would expect it to. It provides a generic two-step authenticator in an app accepted by almost all platforms that use it. During my long use of it, I never ran into any problems with the authentication function itself. I did however run into an ENORMOUS problem when my phone unexpectedly and completely gave out to an internal part failure. All your precious passcodes are accessible only through that ONE device and not something like say, your google account... Personally, I had to lose access to several accounts and wait for direct customer service to regain access. Seemingly against all odds, considering only a few weeks of not have TFA enabled, an account was hacked. Granted, in the end this entirely started with a broken phone, I do believe that this app caused much more hassle than it should of. Considering all the things Google ties into your account, you would think something like an authenticator would fit right in. For better peace of mind go with another authenticator.

  • Works Perfectly Jun 20, 2018

    By I can't think ofa nickname
    Most recent reviews suggest that this app is bugged, though the latest patch must have covered everything, or it’s something out of Google’s controls. As long as you read directions and don’t work ahead of yourself, using the Google Authenticator with whatever it is you are using it for is one of the easiest and safest ways to log in to almost any network or software. 5 stars because there is nothing wrong with it.

    This app has got so much better now that you can scan the QR code and transfer all of the2-step verification secrets what you already have onto another device. Especially useful if you transfer device get a new tablet or just want to give someone else access to your account. The last comment with a little tongue in cheek added.

  • Big problem transferring to new iPhone iOS11.x Jan 17, 2018

    By dig48109
    New iPhoneX unlocked. Backed up my older phone on iTunes and then started the process of restoring the data to the new phone. Google Authenticator. The app refused to install. Warning error [ Unable To Install “Google Authenticator GA” . The app is no longer available in the App Store”. This is actually not true, the app is still available in the App Store. - Ran the latest iOS11.2.2 on the iPhoneX. I wiped the iPhoneX to a factory reset - Ran all app updates on the iPhone6S for all apps. - Ran the latest iOS11.2.2 on the iPhone6S - Did a backup on iTunes twice for iPhone6S - Then did a restore on the iPhoneX . Same problem not able to use “GA”after all that. If I delete “GA” on my iPhoneX and reinstall from the cloud on new phone it opens, but lost all my 2FA sites. This is awful. This is essential for my work security and personal banking. Feature request. Please allow groups so I can sort out 2FA sites by personal , work, banking. Using GA so often that the list becomes too long

    Hey Devs, Backup probably is not what Google Authenticator will have. But, it would be very good to have a sort of backup with List of Websites (or Auth Name) so that we can keep track of what web services we have used google Authenticator with, even if we lost our device. Like list of Websites/App backup to Google Keep may be or Drive etc. Thanks.

    Just a warning to everyone. When you factory set your smart phone obviously back up all of the data first on another digital device. BUT make sure that you back up this app because once it has been deleted off you will lose all of your codes to and you will be locked out of all your online accounts. Google please make this clear to people before they factory reset their phones.

    I have yet to have to reset my phone. After reading the reviews for note 8 and the issues with this app, I am concerned about recovering my data if I reset my phone or try to transfer data. I have not had any issues, yet. I will check back with other's reviews so I can decide whether to continue using this app.

  • It’s an “okay” app. Needs some improvement. Dec 27, 2018

    By 101ToonLink
    The Google Authenticator app is a convenient app to use for Two-Factor-Authentication. (2FA) However, there is still some work to be done to the app. First of all, we need biometric authentication before you can open the app so that if you leave your device unlocked, someone can very easily access the 2FA codes without much trouble. As someone else pointed out, this is a really big security hole that needs to be dealt with. But other than this, it’s a pretty good and simple little app. Just needs a bit more security put in.

  • A serious pain when switching phones Oct 9, 2016

    By Markwoh
    I had this problem on an earlier version of this app. You get a new phone, it is back to square one. There is no restore or saving of codes. It is a great app other than the fact that it becomes a nightmare if you get a new phone or have to restore your phone. They need to incorporate some kind of save system so you don't have to painstakingly disable and reenable every single 2 step verification you had previously.

  • Beware!! Google Auth App not backed up anywhere Jul 20, 2019

    By Philly5648887
    I recently had to replace my phone on two separate occasions and was surprised to find the google Authenticator app data was not restored leaving me to scramble to get into the various accounts I secured with MFA. Be sure to securely save your codes outside the app (IE: 1Password, dashlane) so you don’t lock yourself out of your important accounts. Secondly, Google is a major advocate for security, and it is very surprising that the Google Authenticator app doesn’t allow you to secure access to the app in any form ( IE: pin, Touch ID, password). For the aforementioned reasons, I don’t recommend this app and have migrated my codes to Microsoft’s Authenticator app which allows the use of TouchID and seems to have some iCloud support.

  • May Not Be Possible to Restore from Backups Jul 8, 2020

    By steve-of-indiana
    I had managed to get this app installed on both an iPhone SE & an iPad mini. I had backups of both devices saved to iCloud & iTunes. Someone decided they “needed my iPad” more than I did. After a lot of thought I decided to buy another iPad. I brought the new iPad home & restored from the iCloud backup for the iPad mini. Everything looked good EXCEPT that there was no data for the Google Authenticator app. Nuts! I still have the iTunes backup so I repeated the process & STILL had no data for the Google Authentication app. Now I was getting annoyed but I wanted to have a backup authentication app so I restored the new iPad from the iCloud backup for my iPhone SE & still do not have a working Google Authenticator database on the iPad. I was able to recreate everything by toggling off 2FA on each account, toggling it back on, adding to my devices plus my wife’s devices & repeating for each of my accounts. As someone who has spent close to 50 years working with computers & value redundancy. I am not going through this again. USE OF THIS APP IS NOT RECOMMENDED!

    To think that I used to like this app but now I can't log back in I use my 2 step verification code from Google authenticator and it doesn't work, and I'm pretty sure I can't use a backup code either. Why can't I login if it has my email why not send me my backup codes there? Many people have the same problem so why not fix it

    As basic and barebones as they come and for an authenticator app that's not a good thing. The most surprising thing about this app is that there is no option to lock the app so that it requires a password or biometrics to get in. What's even more dangerous as others have mentioned is that there are no options to securely backup so if you ever reset, break or lose your phone there is no way to restore. My suggestion is to use Microsoft authenticator, much better implementation and options.
