How to Enable Two-Factor Authentication on Facebook, Instagram, and Twitter
While following good account practices such as using strong passwords, taking advantage of a password manager to create complex and unique passwords for different accounts, and avoiding the use of dictionary passwords, ensures your account security to a greater extent, there are instances when even accounts with strong passwords pose a risk of account compromise. For such instances, having another layer of security on your account (say, Two-Factor Authentication), in addition to a strong password, further ensures that your account is less susceptible to attacks. So, to help you do that here’s a guide on how to enable Two-Factor Authentication across different social platforms like Facebook, Instagram, and Twitter.
Two-Factor Authentication or 2FA also referred to as Two-Step Authentication, is a type of Multi-Factor Authentication method that requires users to enter an extra factor (or key) besides their account password to authenticate them and grant them access to their account. Generally speaking, the combination that often works with 2FA includes one factor that is something you know and a second factor that is either something you have or something you are. Talking about the second factor, something you have can be as simple as your mobile phone or a hardware key, whereas something you are can be your biometrics. To give you an example, a second factor that relies on something you have can be your mobile device with a 2FA code generator app, an SMS app (for OTPs), or even a hardware security key (or fob). On the other hand, a second factor that relies on something you are could use your biometrics (face, iris, fingerprint, etc) to authenticate you on your account.
Now that you have some idea of what Two-Factor Authentication is, and how it can help you to increase the security of your account, let’s look at how to enable it on Facebook, Instagram, and Twitter. For this tutorial, we will use Google’s Authenticator app to generate codes and then use them to authenticate your access. So, if you are an Android or iOS user, the first thing you need to do is download the Authenticator app from the Google Play Store or Apple App Store. Once done, follow the steps below to enable 2FA across different social platforms.

You should now see Two-factor Authentication set up on your social accounts. The Google Authenticator app will now generate a random and unique 6-digit token (code) every 30 seconds. So, every time you log in to one of your accounts (with 2FA enabled), you will be asked to enter the code from the Authenticator app. Once you enter the code, you will be granted access to your account. However, do note that the token changes every 30 seconds, so you should enter it instantly to avoid failed attempts. Further, in case you decide to move to a new phone, you will be required to move the Google Authenticator app to the new device for it to continue working on your accounts.
