Google Authenticator adds an extra layer of security to your online accounts by adding a second step of verification when you sign in. This means that in addition to your password, you'll also need to enter a code that is generated by the Google Authenticator app on your phone. The verification code can be generated by the Google Authenticator app on your phone, even if you don't have a network or cellular connection. • Sync your Authenticator codes to your Google Account and across your devices. This way, you can always access them even if you lose your phone. • Set up your Authenticator accounts automatically with a QR code. This is quick and easy, and it helps to ensure that your codes are set up correctly. • Support for multiple accounts. You can use the Authenticator app to manage multiple accounts, so you don't have to switch between apps every time you need to sign in. • Support for time-based and counter-based code generation. You can choose the type of code generation that best suits your needs. • Transfer accounts between devices with a QR code. This is a convenient way to move your accounts to a new device. To use Google Authenticator with Google, you need to enable 2-Step Verification on your Google Account. To get started visit



  • I also lost everything.

    By TheAdsHater
    Oh wonder my phone had broken and had to go through a whole process of rebuilding not a going to be specific, but all my data was lost, everything was fine since all I had was pictures and nothing important that I couldn’t get back but guess what, my first ever account I had created with all my info and logins which I couldn’t log back into, such a shame really. Tried looking for any chat support or anything, didn’t find any, and for those saying “this is exactly what we want”, no, I’d at least me expecting a better support from you guys by now since you’d know this would be happening. Many other apps have already a support system that could help return your account if something like this ever is to happen but I guess you guys are too good for it huh.

  • Even Google agrees that it doesn’t work.

    I have this app from Google to authenticate my login to another Google product, a gmail account. I confirm that the email I’m logging into exactly matches the email listed on the Authenticator. But this was really unnecessary because I’ve used this Authenticator for this email before with success. However, for 2 days now, Google tells me that the code I got from Google is wrong. “Wrong code. Try again.” I waited for a fresh code. I tried with a space and without. I tried everything I could think of, which I knew was unnecessary because I’ve used Authenticator successfully before without having to jump through hoops. But, before I wrote this review, I wanted to be thorough. So, this app worked once, but has been useless for two days. I would recommend avoiding this app if you need to access your email log in and, by extension, any Google Ads you’re running. This app will be terrible for your business!!!
  • Authenticator app

    Good for its purpose, I don’t think it’s missing anything.
  • When it updates you will lose your accounts

    By CryptoPreach
    When it updates you will lose your accounts and if you don’t have backs ups you will be screwed.
  • Bug?

    By Dàrk Śoul
    I would rate the app a 5/5. If it wasn’t because I had downloaded it, and used it for a couple of apps and after accidentally deleting the app, it made a brand new account for the same gmail I had on it and now I can’t log back into it and lost a couple of accounts on other apps and had to start new ones.
  • The codes disappeared almost immediately

    By chiblood
    The codes would show up for only 5 seconds
  • Dissatisfied

    By Dante755
    I used this app and when I tried accessing my account on social media because I didn’t realize that I was to save the first code I can no longer access my account. This app will not generate any new codes. All back up codes don’t work. Even after getting new ones.

    I have no idea how to follow the instructions.
  • Scan a QR code from your phone?

    By 1199hab
    Tough to scan a QR code displayed on your phone, when that is your only mobile device or computer!
