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 mobile 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

Ratings and reviews

It's not the worst authenticator app by any means, and the addition of backup support is a big improvement. However, the interface is severely lacking. There's no ability to adjust the font size or display view, and many entries are difficult to find because important text isn't visible on the screen. Additionally, there's no way to automatically sort or rearrange your entries. You have to manually move them one at a time which is ridiculously cumbersome. Hopefully it gets better!

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!

At some point, the display changed and now it tries to be clever and include the service name. Unfortunately, this takes up half the screen and means I can't distinguish between my several Amazon Web Services accounts without editing each one to find the full name. There doesn't seem to be a way to turn this off, or to change the font size, nor to switch to a landscape view. It's really annoying and needs to be fixed.
