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 current update 5.20R3 is broken. Please fix this ASAP. It's a crucial app! Some details: Upon patiently testing, I found that it takes unusually long time (more than a minute while screen stays black) to load, then display the message "Click to reveal pin". Upon clicking any of the accounts, it further takes long time to reveal the pin. The minute clock of OTP seems to be working/moving, but it displays after a long wait. When it's displayed, the scrolling is possible, otherwise not.

I love the app - works great! But wanted to let you know that after the most recent update it says syncing will continue once your device is online - even when my phone is online and has an active cellular or Wi-Fi connection. Not sure why this is happening or how to fix it. If I use the sync clock feature it just says it's already synced. Thanks so much for a great app and any suggestions to fix.

Although functionally it works there are usability issues that I'm amazed have not been addressed. The one that becomes apparent very quickly is finding a code amongst 20-30 of them isn't easy. Since app can't filter or search the next best thing would be to allow some sort of organisation, one can move entries around, so I'm trying to do so alphabetically, but if I try to drag one of the entries at the bottom upwards the app crashes unceremoniously. Surely I'm not the only one seeing this!
