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

It works fine until you need to transfer codes. Had to factory reset my phone. Transfered the codes to my tablet, verified they went over. Reset my phone, opened the app on my tablet and watched them flash they were there and then gone, they just all disappeared. Now I have to spend a day recovering all of my accounts because your app just decided to remove them.

Great Authenticator. Don't know why it gets a lot of bad reviews. Had it for a year already. No issues. The codes auto sync across all platforms. I can open the app on my Android and iPad. All the codes are there. If I lose my phone, I can just open the app on my iPad and works just fine. Works as advertised.

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.
