How to Set Up Two-Factor Authentication (2FA) on Various Social Networks

Protect your social media accounts by adding 2FA verification, it's easy!

2fa Social Apps Featured

It’s quite common these days to hear stories of users who have had their accounts tampered with. As a precaution, you may want to enable extra security measures, such as two-factor authentication (also known as 2FA), when using popular social media apps. Since every social network has its own design, you may not be able to find this security option easily, but this guide shows you how you can quickly enable 2FA for most popular social apps.

What Is Two-Factor Authentication?

Two-factor authentication (2FA) is an extra layer of protection added to ensure that those trying to get access to an account are who they say they are. First, your password and username are entered. Then, instead of instantly gaining access to the account, you are required to provide another piece of information – for example, a code.

You can get the code via text messages or a specialized authenticator app that you can install on your mobile device. Once linked to your accounts, the app will generate a stream of random codes to be utilized whenever needed. This method does not require an Internet connection to give you the code.

Facebook

To set up Facebook’s two-factor authentication, you’ll need to go through your account’s settings, whether you’re doing so on your PC or mobile. (We used an Android phone for this entire guide). Steps may vary depending on which device you’re using.

PC

  1. Navigate to Facebook in your browser, then click on the downward arrow in the upper-right corner.
  2. Select “Settings & Privacy.”

  1. Select “Settings.”

  1. Select “Security & Login” from the left side of the display.

  1. On the right side, scroll until you find the “Two-factor authentication” option and click it.
  2. You will be presented with 3 options. The recommended option is to use an authentication app to generate verification codes for more protection. The second one is Text Messages (SMS). This method uses texts to send verification codes to your phone after you’ve logged in to your Facebook account. The third one is a Security Key, which is a USB- or NFC-based piece of hardware that plugs in to your computer or mobile device to authenticate.

  1. To take the recommended route, click on the “Use Authentication App” button. A QR code will be generated on your display.

  1. Open the authenticator app which you previously installed on your phone and scan the QR code. An authentication code will be generated by the app. It needs to be copy-pasted to your Facebook desktop app. That’s it! Two-factor authentication is now on.

If you go back the same route – “Settings & Privacy -> Settings -> Security & Login -> Two-factor authentication” – you’ll notice that you can now add a backup method so that you can log in even if your security method is not available. This includes Text Messages (SMS), Security Key and Recovery Codes. It may be a good idea to set one of these up just in case you can’t access your account the usual way.

Mobile

If you’re using Facebook on a mobile device, follow the below instructions:

Frequently Asked Questions

1. Do I need to reset 2FA if get a new phone?

It depends. If you have Google Authenticator as your primary 2FA method on a certain account, you can transfer your current 2FA configuration to your new device. On the other hand, if your 2FA method is SMS and you have the same phone number on the new device, you won’t have to make any updates. If your new phone has a new number, then you’ll need to set up 2FA for the new phone number on most of your accounts.

2. What are some of the best authenticator apps out there?

Google Authenticator is a popular solution, but there are many other options to choose from. Check out our list here.

3. My six-digit authentication code is not working. What can I do?

The six-digit codes you create using the authenticator app expire after a certain amount of time. Make sure you use the code before it expires. On the other hand, note that authenticator apps tend to rely on the time set on your device when they create the code. If the time on your mobile doesn’t match the time on the PC, the code will not work. Therefore, you may need to make sure the two match by modifying one of them.
