Two Factor Authentication has been around for quite some time now and is still considered one of the best ways to protect online accounts from unauthorized access. Although it isn’t mandatory to use 2FA, most websites, apps, programs, games, and clients, recommend it as something you should take the time to enable and backup. Especially if you are syncing your Firefox information between your devices.

A detailed explanation of 2FA from wikipedia can be found here.

2FA comes in a variety of different formats, some forms allow you to use your phone (text message) or email to verify your identity, whilst others use special applications which generate codes to protect your account. Below are 2 of the most popular 2FA apps available for both iOS and Android.

Now that you have a good understanding of 2FA and an app to use, you can add 2FA protection to your Firefox account. Unfortunately, as the feature is currently still in roll out phase, you may not be able to access 2FA options from directly from your browser and account page. If this is the case for you, you can instead use the following link to go directly to the Firefox 2FA page.


Once you are on the Firefox 2FA page, scroll down to Two-Step Authentication and click Show to expand the section. Now click Verify.
