In today's digital world, protecting your Mozilla account is essential for online security. Two-step authentication helps you with that by adding an extra layer of protection that will make it harder for someone else to sign in to your account, especially when your password is compromised.

Once you enable two-step authentication, when someone attempts to sign in to your account with your password, Mozilla will also ask for an authentication code from your authentication application for proof that it’s really you.

How do I enable two-step authentication?

Step one

Before you get started, download one of the following authentication applications:

Step two

Now that one of the applications is installed, we can set up two-step authentication in Firefox:

  1. Click the menu button menu button retina at the top right corner.
  2. Click Mozilla accounts from the menu (it will show your email address if you're signed in).
  3. Click Manage Account. The Mozilla accounts Settings page will open.
    Manage your account
  4. Under Security, click the Add button next to Two-step authentication. A QR code will display.
    FXA Security
    Add 2FA
  5. Open the authentication app of your choice.
  6. Use the app to take a photo of the QR code, or click Can’t Scan Code to display a code to enter into the app. (If you are entering the code manually on Authy Mobile, search Firefox 100 to get the latest logo.)
  7. Enter the code generated by the app into the Mozilla accounts Two-step authentication section and click Continue.
    Note: Download or print your backup authentication codes and keep them in a safe place in case you lose access to your authentication application.
  8. Copy one of the backup authentication codes to confirm that you have saved them and click Continue.
  9. Paste the code and click Finish.

The setup of your two-step authentication is now complete!
