Best Multi-Factor Authentication for Mozilla Firefox

How to use two-factor authentication with your Firefox browser for better online security

What is two-factor authentication?


Two-factor authentication, or 2FA, is a type of multi-factor authentication and adds an extra layer of security to online accounts by requiring an additional login step. After entering a password to log in, you’ll be asked to provide a security key which can come in the form of a numerical code, barcode, QR code, or other piece of information. Only by providing the right information will you be granted access to the account.

If a password is stolen or leaked online by a hacker and someone else is trying to log in to your account, they won’t be able to without the 2-factor authentication!

How does two-factor authentication work?

Provide login credentials

The first half of the authentication process involves you entering your account login and password.

Passcode is sent to mobile device

Your chosen authenticator app will generate a unique verification code on-screen as a QR code to scan or numerical code via text message. These tokens will vary across different 2FA apps..

Verify the token

Your mobile device will then prompt you to confirm the unique token. This can be done by scanning the QR code or entering the numerical string sent to your mobile device.

Why use two-factor authentication?

The right two-factor authentication app makes browsing with Firefox more secure, without slowing down your day.

Add extra protection

Worried about phishing attacks or malware? Two-factor authentication keeps hackers locked out.


Simplify online security

Combining 2-step verification with a password manager eliminates the need to remember your passwords!


It's free!

Many popular two-factor authentication options, including LastPass Authenticator, can be downloaded for free.

How to set up two-factor authentication on Firefox

Choose an authenticator.

There are many options when it comes to two-factor authentication. The most popular options include apps that can be downloaded to your smartphone from your app store, like LastPass Authenticator, Google Authenticator, or Authy. LastPass supports many two-step authentication apps.


Enable it for your accounts.

Many websites and apps, including banks, social media, email, password managers, and more, offer the option to turn on two-factor authentication. In your Firefox account settings under Manage Account, look for security options and turn on two-factor authentication. Hit the enable button, then select your chosen two-factor authentication app for your account.


Log in with extra protection.

The next time you log in to the account, you’ll enter your password and be asked for your two-factor authentication, too. Enter the code from the app on your phone or tap the approval message sent to your smartphone.

“I like that LastPass is easy to use and intuitive. It integrates well with all websites and allows me to keep secure encryption for all my personal and work-related accounts. It allows me to organize folders, share with others, and only memorizing one master password for all of those while keeping encryption secure is a relief.”

“I use LastPass both corporately and personally. It allows me to securely store and share passwords with my family and co-workers in separate environments and happily generates random secure passwords for me, which prevents me from re-using the same one.”

“I have been with LastPass for about two years now and it's one of those apps that you wonder why it took so long to start using. The absolute frustration of trying to keep track of passwords manually was so stressful. LastPass takes the stress away. It is extremely easy to use in my opinion, and has some great security features.”
