Google authenticator

If you set up 2-Step Verification using SMS text message or Voice call and also want to be able to generate codes using your mobile device, you can use the Google Authenticator app to receive codes even if you don’t have an Internet connection or mobile service.


To set this up, first you need to complete SMS/Voice setup. Then, follow the directions for your type of device explained below.


Turn on 2-Step Verification

When you enable 2-Step Verification (also known as two-factor authentication), you add an extra layer of security to your account. You sign in with something you know (your password) and something you have (a code sent to your phone).


Set up 2-Step Verification

  1. Go to the 2-Step Verification page. You might have to sign in to your Google Account.
  2. Select Get started.
  3. Follow the step-by-step setup process.

Note: To ensure that you can access your account in the future, add an email recovery option as well.
