Two-step authentication adds extra security by making it harder for someone else to log into your account, especially if they steal your password.

When you enable two-step authentication, when someone attempts to log into your account with your password, Firefox will also ask for a verification code from an app that’s on your phone 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

Then follow these steps to set up two-step authentication in Firefox:

  1. In the Menu bar at the top of the screen, click Firefox and then select Preferences or Settings, depending on your macOS version.Click the menu button Fx89menuButton and select Settings.
  2. In the Firefox Account panel, click Manage account.
  3. Expand the Two-step authentication section.
    This feature currently might not appear for all users. If it isn’t visible, add &showTwoStepAuthentication=true to the URL and refresh the page.
  4. Open the authentication app of your choice on your phone.
  5. 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.
  6. Enter the code generated by the app into the Firefox Accounts Two-step authentication section.
  7. Download or print the recovery codes and keep them in a safe place in case you lose access to your authentication application. Setup is complete!
