How to Set up two-factor authentication for Facebook

Do you want more security for your online accounts? Techjaja shall bring you a three part series to help you secure you online accounts from Microsoft, Google and Facebook.

So how does two-factor authentication work? In a nutshell, it requires not one but two pieces of privileged information before granting access to an online account.

Let’s say you’ve already set up two-factor authentication for your Facebook account, and now a hacker halfway around the world is trying to break into your account . He has your email address and even your password, but he doesn’t have the second element of the authentication process.Enabling two-factor authentication for your Facebook account is a snap. Just log into Facebook and click on the blue gear icon in the top-right corner, then click on your Account Settings menu.

Next, select the Security section from the navigation bar on the left-hand side of the screen, and switch on the Login Approvals feature (Facebook’s term for two-factor authentication) by clicking the appropriate checkbox. Facebook will walk
you through the process from here, explaining how to receive and type in a unique alphanumeric code every time you want to access your account.

What we call two-factor authentication Facebook calls Login Approvals, and it works great.

To get that code you’ll need to either download a mobile authenticator app that generates codes every time you log in, or give Facebook your cellphone number so it can send you authentication codes via SMS. I recommend going the authenticator app route. It’s simple to use, and you don’t have to wait for Facebook’s servers to text you your code. Plus, you can also add a cellphone number as an additional backup if the app fails to work.

Facebook wants you to use the Code Generator in the Facebook mobile app to generate authorization codes, but you can trick it into letting you use any third-party TOTP authenticator you like.

 In its mobile app, Facebook built in a neat Code Generator feature that generates TOTP codes for your account, but you can use any old TOTP authenticator app if you’re willing to subvert Facebook’s setup process.If you’re using Google’s mobile authenticator app to manage two-factor authentication across multiple services, for example which is a great idea you can set it up to provide authenticator codes for your Facebook account too.

Simply start the Code Generator setup process—click the Set up Code Generator link under Login Approvals in your Facebook security settings—and when the time comes to open the Facebook mobile app, click the Having trouble? link. Facebook will ask you to click a big blue Get Key button and enter the provided 16-character key into your Facebook mobile app, but you can enter it into almost any authenticator app—including Google’s—and it will still work.
