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

After an update a year or 2 ago, codes no longer automatically refresh after the timer completes. Instead, you must now manually refresh by pulling down on the screen, rotating the phone to switch from portrait to landscape (or vice-versa), or holding down on an entry to edit it (which will still refresh all entries). The basic functionality of an authenticator app is to display a valid code which does not currently function properly.

Got really tired of things not working correctly. Cloud syncing refused to work. On the rare occasion it actually did sync it would add all the entries from the cloud as duplicate entries. Lacking in a lot of features and it's a pain trying to migrate to a different app. I switched to Aegis Authenticator and it was the best decision I ever made. Took a while to switch my accounts to Aegis thanks to Google not allowing you to export to other apps, but no regrets.

Was fine for over a year then all of a sudden my codes won't work on any website I use it for. I tried syncing but it keeps telling me "it appears to be synced already." I made sure it was updated. I transferred it from one email to another and I was able to log in to one account. Tried logging into the same account again and couldn't do it. Uninstalling and reinstalling fixed it for now but I'm not optimistic.
