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 authenticator application as proof that it’s really you.

How do I enable two-step authentication?

Step one

Before you get started, install the authenticator application of your choice. Here are some options (this is not an exclusive list of supported applications):

• Ente Auth: GitHub (Windows, Linux, Android & macOS), App Store (iOS), Google Play & F-Droid (Android). The basic web version is only for those who downloaded the above apps. Includes backups.
• Zoho OneAuth: Android, iOS & macOS, Windows. Includes backups.
• Twilio Authy Authenticator: Android, iOS & macOS. Includes backups.
• Google Authenticator: Android, iOS & macOS.
• Duo Mobile: Android, iOS & macOS.
• FreeOTP: Android, iOS & macOS.
• KeepassXC: Linux, macOS, Windows.

Step two

Now that one of the applications is installed, you can set up two-step authentication for your Mozilla account:

1. Go to your Mozilla account settings. To get there, either
   • Navigate directly to accounts.firefox.com, or
   • Click on your Mozilla account in the Firefox toolbar (your avatar icon) and then click Manage account, or
   • Click the menu button to open the menu panel. Click on your Mozilla account in the menu (it will show your name or email address if you're signed in) and then click Manage account.

     

2. On the Mozilla accounts page, under Security, click the Add button next to Two-step authentication.

   

   • A QR code will display.

   

3. Open the authenticator app of your choice.
4. Use the app to scan the QR code with the camera and register your Mozilla account in the app.
   • You can also click Can’t scan code? to display a code to enter into the app. (If you are entering the code manually on Authy, search Firefox 100 to get the latest logo.)
5. Enter the code generated by the authenticator app into the field below the QR code, and click Continue.

   

   • A list of one-time use backup authentication codes will be displayed. Saving these codes is required to complete setup of two-step authentication for your Mozilla account.

   

   Note: Download or print your backup authentication codes and keep them in a safe place, in case you lose or cannot access your authenticator app. This is an important step to reduce the risk of account lockout.

6. Save the backup authentication codes, and click Continue.
7. Paste one of the codes to confirm that you have saved them (if you haven't, click the arrow on the left to go back to the list of codes).

   

8. Click Finish.
   • The setup of two-step authentication on your Mozilla account is now complete!
