Why is 2FA important? It protects your accounts from unauthorized access!
We'll jump right into enabling 2FA for Facebook. Other social media sites will have something similar so I will provide a few links to their FAQs for that information.
How to enable 2FA for Facebook
1.) While logged into your Facebook account, click on the chevron down icon in the top right corner to get a menu. Click on "Settings" to take you to your Facebook settings page:
2.) Next, click on "Security and Login" located in the navigation on the left.
3.) Then, find the section that says, "Two-Factor Authentication", and click on the "Edit" button:
4.) For this part, I recommend using an authentication app like Google Authenticator, but for the ease of this tutorial, we'll go with text message instead. To proceed, click on "Use Text Message (SMS)".
5.) Next, in the pop up window, enter the mobile (cell) phone number you would like to use to get the codes as text messages:
6.) Then when you're done entering your mobile phone number, click the "Continue" button:
7.) Now, wait for a text message to be sent to your phone from Facebook. This should contain a 6-digit code that you will then enter in a similar screen like below. Once you enter the 6-digit code, click the "Continue" button.
8.) Then, after waiting for the two-factor authentication to become enabled for the account, you should see the following message. This means that your Facebook account now has 2FA (two-factor authentication). Now click the "Done" button.
9.) When you click the "Done" button, you'll be presented with the following pop up window. Click "Not Now".
10.) Now, you should see something similar to the below screenshot. If you do, then that means you're done enabling 2FA! Your account is now protected. If anyone, even you, tries to login to your account, they will need to enter a 6-digit code that will be sent as a text message to your phone. So make sure you have your phone on you!
