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

Ratings and reviews

The authentication works, but the user interface clearly had zero thought put into it whatsoever. Even the very most basic features like the ability to sort the sites for which you are storing authentication information are missing. If like me you need many authenticated sites, enjoy trying to find them at random because the only sort option is chronological. And now it has the same meaningless, indistinguishable icon as every other Google app to make it hard to even find and open. Stop it!

Until recently, this was an acceptable authenticator; it worked, and the UI wasn't awful. However, as of two days ago, the one-time passcodes no longer cycle when their time slots expire, making them useless. I must close and reopen the app to get fresh passcodes. Consequently, I have to race to enter the passcode before its slot times out, or else close/reopen the app. This is stupid. There's no meaningful way to get customer support or report bugs, and no relevant "help" for this issue.

Okay, not sure why it changed, but I went to use the app and now I can no longer tap and hold to copy the code to my clipboard. I mean, sure it's great that I can now rename and change the order of all of my accounts, but I have a huge problem with remembering numbers and now that one basic accessibility option is no longer available and it can take two or three tries and retries for me to get it right! Bring back that accessibility feature and I'll up the rating!
