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.
* To use Google Authenticator with Google, you need to enable 2-Step Verification on your Google Account. To get started visit http://www.google.com/2step Permission notice: Camera: Needed to add accounts using QR codes

Ratings and reviews

App no longer appears in my app drawer or on my home screen, and when I search my device it doesn't appear. However, when I search the play store it says it's installed and gives me the option to open the app. I'll be really upset if something happens and I have to go through some pita process to recover a bunch of accounts that use two-factor with Google authenticator.

Works well about half the time. I use this for a lot of apps at work and often times I'll put in a number, only to get an error saying it's expired when it isn't. One time at complete random, it started giving an error that it has no permissions to my camera, when I changed absolutely nothing! Every single setting said it had permission. I uninstalled and reinstalled, that didn't fix it. The workaround is to scan the QR code with a barcode scanner outside of this app and open in the app.

The app has completely failed on my phone. All of the app accounts that I had connected to it, and that demand it's use for 2fa, have disappeared, and I can't even figure out how to reconnect them. It really sucks when you have money in accounts that require an Authenticator generated code to gain access to them so you can transfer or use that money, but instead, you can't do squat! Your money is just stuck there. It's unbelievable!
