About this app

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.

Ratings and reviews

Latest update knocked codes out of sync and they removed the ability to resync codes. Little to no support. If you look up how to fix, it says you need to sync your phone to your network provider now. Well, I've done that, reverse done that, tried changing timezones and reverting back, rebooting my phone, etc. The app would be 4 or 5 star, except for limited support and a bug from last update that hasn't been fixed in over 2 months. I literally get 10 seconds to enter code now.

Like everyone is saying, the most recent update knocked codes out of sync. The right code is only displayed for about 10 seconds. My phone's time is correct, and I have even tried adjusting my phone time forward by various increments but it doesn't work. Google responses to these reviews have been ignorant and unhelpful; they have no clue what they're talking about. WHAT WORKS FOR ME is to force quit the app (the ||| button on your phone, then swipe up on the app) and reopen it EVERY TIME.

Like most things, Google these days just doesn't work like it used to. After the most recent update trying to add an account using a barcode or entering the setup code doesn't do anything. There's no way to add new accounts. If you are in the same spot, just download the Microsoft authenticator app. It worked flawlessly the first time on the same QR code and I've used it for years.
