When it comes to digital security, one of the best ways to protect yourself is to use two-factor authentication. Most apps support it today, including Facebook, a site where the more integrity you can gather, the better. But of the two 2FA options available to Facebook, only one should be used because the other will share your phone number with the world, a major privacy event.
The two options you get for Facebook use either text messages or an authentication app, the former being the culprit you want to avoid. For one, SMS-based 2FA is about the least secure form of 2FA available. If you use your phone number with Facebook's 2FA, or even just list your number via Facebook in some way, Facebook will use your number to recommend your profile to contacts, it will be searched and it can be shared with Instagram and WhatsApp.
If you've already configured 2FA on Facebook with your phone number, we'll show you how to completely eliminate your numbers from the site, and then go through the 2FA configuration with a third-party authentication app instead. An authentication app acts as another password for Facebook to use to confirm your identity. Authenticators use their own encryption and security measures that blow SMS out of the water. Best of all, you don't have to spend a dollar on these apps if you don't want to.
: Choose a third party authentication app
Before we even open Facebook, you can save yourself sometime on the road by downloading a third-party authentication app right now. Keep in mind that you can download this app on either the iPhone or Android phone that you use Facebook on or a secondary device to increase security. It is up to you to weigh the safety and convenience of each option.
Which app you choose is also up to you. Facebook mentions both Google Authenticator and Duo Mobile, but there are many more options out there, such as Authy (our favorite), all with their own advantages and disadvantages. If you need help choosing the right 2FA app for you, check out our summary of the best programs.
Step 2: Remove your phone number from Facebook
Trust us, this will thrive. If your phone number is linked to Facebook in any way, shape or shape, the company reads it. You are better off protecting your privacy by removing the number completely.
Touch the menu icon for burgers, and then tap "Settings and privacy." Select "Personal shortcuts" from the list and then select "Update your personal information" under Account Security . Then tap your phone number and select "Delete" on the following page.
Then enter your Facebook password in the field provided and then press "Delete phone". Give Facebook a minute to crush this number from your account and presto! You are now the proud owner of a myriad Facebook. This means that if you had 2FA set with this number, you no longer have 2FA enabled. But we are in the process of setting up 2FA with a much safer method.
To set 2FA, open Facebook and then press the menu icon for the hamburger. Touch "Settings & Privacy" and then select "Shortcuts". Scroll down and press "Use two-factor authentication".
