What is Google Authenticator?

Google Authenticator is a free security app designed to protect your accounts from password theft. It adds an additional layer of security by generating unique codes on your smartphone. You’ll need to input these codes alongside your password to log into your accounts, making unauthorized access much more challenging.

This app works with many accounts, including your Google account, social media accounts like Facebook, and cryptocurrency exchanges like Coinbase, making it a versatile tool for digital security.

Backing Up Google Authenticator

The Google Authenticator app generates essential security codes that, if lost, could potentially lock you out of your accounts. Thus, it is crucial to back up your Google Authenticator codes.

The app now automatically backs up your codes to your Google Account, meaning you can restore them to a new device from the cloud even if you lose your phone. But it’s important to note that these backups are not end-to-end encrypted. While Google plans to provide end-to-end encryption, it is still in progress as of now. If you require a higher level of security, consider keeping a separate, secure copy of your backup codes.

How Do I Set up Google Authenticator on a New Phone?

Google now allows users to backup their Google Authenticator codes to their Google Account. Therefore, the process of setting up Google Authenticator on a new phone has become quite straightforward if you’ve already sync’ed your account. Here’s how you can do it:

  1. Download Google Authenticator: Begin by downloading and installing the Google Authenticator app on your new phone. You can find the app on the Google Play Store for Android phones and the App Store for iPhones.
  2. Log into Your Google Account: Once installed, open the app and sign in using your Google account credentials. Remember to use the same account you were using on your old phone for Google Authenticator.
  3. Your accounts will then be sync’ed: When you sign in with your Google account in the Authenticator app on a new device, all your authenticator accounts will be synced over.

Please note that these backup codes are not end-to-end encrypted. This means that, while unlikely, it’s technically possible for someone at Google or anyone who can compel Google to give them access, to see your backup codes. However, Google has announced plans to provide end-to-end encryption in the future.

Where Do I Get the QR Code for Google Authenticator?

The QR code for Google Authenticator is typically provided by the website or service for which you are setting up 2FA. Here are general steps on how you can get the QR code:

  2. Enable 2FA: Look for an option to enable 2-factor authentication. If this is the first time you’re setting up 2FA, you may need to provide additional verification, such as answering security questions or providing a phone number.
  3. Select Authentication Method: The service will ask how you want to receive your 2FA codes. Choose the option for a mobile application, which should prompt the service to generate a QR code.
  4. QR Code: This QR code is what you’ll scan with the Google Authenticator app. It associates your account with the app so that it can generate the correct codes.
  5. Scan with Google Authenticator: Open the Google Authenticator app on your smartphone and tap the plus (+) button. Select “Scan a barcode,” and use your phone’s camera to scan the QR code displayed on your computer screen.
  6. Verify Setup: After you’ve scanned the QR code, the Authenticator app will begin generating codes. Enter one of these codes into the website or service to verify the setup. Once the service confirms that the code is correct, the setup process is complete.
