That’s why Twitter and other companies use creative phrases to describe their implementation of this additional layer of security.
so here you go;
1. Log into your Facebook account using a web browser; At the top right of the Facebook display window, you will see an icon in the shape of an arrow pointing downward. Click on that icon.
2. A menu will drop down from the arrow icon. You can use this menu to create a group, set up a business page, and view your account settings. That lattermost option is what we’re looking for.
Scroll down and click on “Settings.” It should be located right under “News Feed Preferences.”
3. The page for your account settings will load up. Here you’ll find some basic information about your profile, including your name and registered email address.
To the left, you’ll see a sidebar where your account settings are grouped into a number of clickable sections. Click on the “Security” section, which should appear just under “General.”
4. The Facebook Security page serves as the central hub for a lot of great features. It is here that you can manage your FB apps, get an alert sent to your device when someone attempts to log into your account, and even manage an OpenPGP key to enable encrypted notifications.
We’re interested in “Login Approvals.” Click on that feature. It should appear the second from the top right under “Login Alerts.“
5. Some text will appear asking you to require security codes whenever you attempt to access your account from an unknown computer, device, or browser. Check the box located next to the text.
If you have not save your mobile phone number with Facebook, a dialog box will appear informing you that login approvals uses your mobile device to send you security codes. You will therefore need to set up your Facebook account on your device. Click on the “Get Started” button to begin the process.
6. Another dialog box will appear. Select which type of device you use. Once you do, some text will inform you that you need to have the latest version of the Facebook mobile app installed on your device. You can download the app here: https://www.facebook.com/mobile .
Once you have set up your account on your device using the Facebook mobile app, return to your web browser and click on the “Continue” button in the Facebook dialog box.
7. Facebook will then prompt you to activate Code Generator, a means by which to receive security codes on your mobile device. It works very similar to Google Authenticator in that its codes are time-sensitive.
On your Facebook app, click on “Menu.” It should appear as three horizontal lines near the top of the display window.
8. Scroll down to the “Help & Settings” section and click on “Code Generator.” It should have a circular image of a locked padlock next to it.
9. Click on “Activate,” which will then successfully enable the Code Generator on your phone.
10. Once Code Generator is set up on your device, return to your web browser and click on the “Continue” button to turn on security codes for your account.
11. At this point, Facebook will ask you to enter the security code that appears on your mobile device via Google Authenticator into the web browser text field. Enter in the code. If you submit the correct number combination, a green check mark with the text “It worked!” will appear next to your entry.
Hit the “Confirm” button to submit your entry.
12. Another dialog box will then appear stating that in the event the Code Generator does not work, Facebook will send you security codes via SMS text messaging to your phone. Click on the “Continue” button
13. Facebook will then ask you to add your mobile phone number to your timeline for this backup security code feature. Enter your number into the “Phone number” text field and click “Continue.”
14. In the new dialog box, enter in the code that you should have received via SMS text messaging to your device and click on the “Confirm” button.
15. Almost there! For security purposes, Facebook will ask you to re-enter your password in a dialog box. Do so and click “Submit.”
16. As the final step, a new dialog box will appear indicating that you will now receive security codes whenever you attempt to log into your account from a new browser.
You have the option of disabling security codes for the first week. I advise against this. You want the added layer of security now.
With that in mind, check the box labeled, “No thanks, require a code right away” and click the “Close” button.
17. And you’re done! Now whenever you attempt to log in to your account via a new web browser, this window will appear after submitting your username and password.
You should also receive a notification to your phone prompting you to enter a security code that appears on your device via Code Generator. Enter that code into the text field and click “Continue.”
(NOTE: You will have the option of telling Facebook to remember the browser you are using so that you don’t need security codes the next time you log in with that computer, browser, or device. Save that browser ONLY if the computer/device is private and not shared with people you do not trust.)
Once you’ve completed that step, you will be directed to your Timeline.
