Google Authenticator works with 2-Step Verification for your Google Account to provide an additional layer of security when signing in.
With 2-Step Verification, signing into your account will require both your password and a verification code that you can generate with this app. Once configured, you can get verification codes without the need for a network or mobile connection.

Features include:
- Automatic setup via QR code
- Support for multiple accounts
- Support for time-based and counter-based code generation
- Transfer of accounts between devices via QR code

To use Google Authenticator with Google, you need to enable 2-Step Verification on your Google Account. Visit to get started.

Don't use this app, use Authy instead

I always use a Two-factor Authentication app, Two-factor Authentication is really important, but I do not recommend this app, because if you get a new phone you have to reset Two-factor Authentication on all your accounts all over again, also if your phone breaks you're locked out of your accounts. I use Authy, because it does the same thing as Google Authenticator, but you can turn on a setting to let Authy back up your tokens in the cloud with a password only you know, so that if your phone breaks you're not locked out of your accounts. Also with Authy it has an option to enable multi device support. Also if you want to be extra secure you can set up a PIN Number and Face ID on Authy, Google Authenticator doesn't have this option.

Zero stars - avoid at all costs

1) there is no support
2) it requires you to print out codes and remember where you put them or store as screenshots, about the least secure thing I can think of
3) if you lose those the app becomes a brick
4) if you lose the original device you installed it on, the app becomes a brick
Seriously, save yourself heartbreak and never use this. Read the reviews. I can’t get a new passport now because my ID is tied to this stupid app, and there is no way to contact google for help on this, the user is completely abandoned.

Finally an export

Google are arguably the slowest people to update their apps. Authenticator has looked and felt like something from the 90’s for a long, long time.

This update has not only modernised the apps general look but added exporting, a long overdue feature.

Thanks guys, you’re slower than anything I’ve ever experienced in my life but when you finally act you do a good job.
