There’s nothing more important than your online security in this digital era, from maintaining your privacy to protecting your accounts and passwords. There’s always someone willing to take advantage of an improperly secured Facebook account, and it shouldn’t be yours!
Aside from standard security protocols (a perfect password), Two-factor Authentication (2FA) provides a code to a secondary account or phone number before you get access. When you’ve correctly set up 2FA on Facebook, you will receive an SMS or email message with a one-time entry code. Typically numeric, this code expires after several minutes, and it is not related to your personal information in any way (it’s not your birthday or the last 4 of your SSN).
2FA, like other forms of security, isn’t without its flaws, of course. There may come a time when you’re safer doing away with the authentication than maintaining it. If someone does have your phone, they can easily log in to your Facebook account using the 2FA feature. Many times, all it takes is clicking on “This was me” to bypass the unique and secure password you’ve set up.
This article reviews setting up 2FA on your Facebook account and also teaches you how to remove it. It mentions a few other security features the social media giant offers.
How to Enable 2FA on Facebook
There are several ways you can enable 2FA on Facebook. The following sections show you how to enable two-factor authentication on various platforms.
How to Enable Facebook 2FA using a Web Browser
If you don’t have two-factor authentication enabled already, follow these steps:
- Log into “Facebook” and select the “downward arrow” icon in the top-right section, then Choose “Settings & Privacy.”
- Click on “Settings.”
- Choose “Security & Login” in the left-hand menu.
- Scroll down and click on “Use two-factor authentication.”
- Click on “Use test message (SMS),” then follow the prompts and assign the contact to receive your 2FA codes.
Now, anytime you log into Facebook, you’ll need to verify a random code sent to that security method. But do beware; if you do not have access to that method, you may be unable to log into your Facebook account in the future.
How to Enable 2FA on the Android Mobile App
If you’re an Android user and need to enable Facebook 2FA while on the go, follow these steps:
- Open the “Facebook“ app and tap on the “three horizontal lines“ in the upper right-hand corner. Then, tap on “Settings & Privacy,” and then choose “Settings.”
- Select “Security and Login.”
- Tap on “Use two-factor authentication.”
- Choose the option to to turn 2FA on. Then, verify that it is on (it gives you the option to turn it off).
How to Enable 2FA on the iOS Facebook App
iPhone users can follow these steps:
- Open the “Facebook” app on your iPhone and tap on the “three horizontal lines” in the lower right-hand corner.
- Select “Settings & Privacy” followed by “Settings.”
- Choose “Security and Login.”
- Tap on “Use two-factor authentication.”
- Tap “Turn On” or “Turn Off” to enable or disable 2FA.
After you’ve enabled 2FA, verify that the phone number is one where you can receive text messages and alerts.
How to Disable 2FA
If 2FA is no longer working for you or you need to turn it off for some reason, you can disable it by following the below steps.
- Log in to “Facebook,” then select the “Settings” tab followed by the “Security & Login” page under the “Settings” tab.
- Click ‘Edit‘ next to the 2FA option. Next, you’ll need to input your current Facebook password.
- Now you can click ‘Turn Off‘ to disable two-factor authentication.
Now, follow the prompts to remove 2FA. Once complete, you can log into Facebook without having a verification code.
Things to Do Before Activating 2FA
As stated above, 2FA is an excellent security feature, but there are some things you need to do first to ensure that you won’t have trouble logging in later.
2FA is so secure that even you (the account owner) may have difficulty logging in if you don’t set things up correctly. The first thing you need to do is verify that all of your contact information on Facebook is up-to-date.
Verify that Your Facebook Contact Details are Correct
- Access Facebook 2FA settings using one of the device methods (browser, Android, iOS) until you get to and select “Use Two-factor authentication.”
- Select “Manage” next to your “mobile number” or choose “Use text message (SMS)” if not already set up. Double-check and possibly update your phone number.
- If using the built-in 2FA option, nothing more is required. When using a third-party 2FA option, Choose “Turn Off.”
Note: The built-in Facebook 2FA option prevents the ability to use that same phone number for changing your password, which is why Facebook recommends using a third-party 2FA app.
Keeping your phone number up-to-date is crucial to your security and your ability to gain access to Facebook on a new account. If this number is outdated, you won’t receive a security code, effectively locking yourself out of your account. You should also update your contact information every time you change your phone number.
Facebook Built-In 2FA Alternatives
If you don’t have a phone number or want to use the built-in 2FA anymore, you aren’t entirely out of luck. Facebook offers an alternative way to protect your account.
How to Use Third-Party 2FA Verification Apps for Facebook
A quick and easy alternative to the Facebook 2FA option is a third-party authentication app. Google Authenticator is a widespread and trusted application available for iOS and Android users, but you’re free to choose any 2FA app you want, such as Authy for Facebook.
- Access Facebook 2FA settings using one of the device methods (browser, Android, iOS) until you get to and select “Use Two-factor authentication.”
- Select “Use authentication app” instead of “Text Message (SMS).”
- Facebook will give you a “scannable QR code” and an “alpha-numeric code” to set up your third-party app. Follow the instructions and click “Continue.”
Now, you can log in to Facebook with 2FA using a third-party app without needing a phone number.
How to Use Facebook Friends to Unlock Your Account
Another Facebook 2FA alternative is to use your friends. Although this method is mainly used when you get locked out of Facebook, it still serves as a 2FA method since it uses keys. Your trusted friend sends a code and URL from Facebook to help you log back in.
- Access Facebook 2FA settings using one of the device methods (browser, Android, iOS) above until you get to the “Security and Login” menu.
- In the “Setting Up Extra Security” section, select “Choose 3 to 5 friends to contact if you get locked out.”
- If you haven’t previously added any friends, select “Choose Friends.”
- In the popup, click on “Choose Trusted Contacts.”
- In the next popup, type in each friend’s name and select them from the search list. After selecting the first one, you’ll type the next one to repeat the process.
- Once you have three to five friends selected click on “Confirm.”
Deprecated/Removed 2FA Options
In the past, Facebook included the “Add a Backup Method” section under “Security and Login,” which had universal two-factor authentication (U2F) via a browser or 2FA-supported USB devices, as well as near-field communication (NFC) support, but it no longer includes them as an option. The “Add a Backup Section” got replaced with “Setting Up Extra Security.”
First off, Chrome deprecated the U2F security protocol in support of FIDO2/WebAuth security keys. Other browsers have followed in their footsteps. Second, Facebook decided to let you use three to five “trusted” friends to help unlock your account, which you’ll find under the “Setting Up Extra Security” section.
Therefore, you only have two login options for Facebook: 2FA (via SMS or an authenticator app) and friends.
How to Update Your Phone Number
2FA mainly relies on your phone number unless you’re using an authenticator app. But, what do you do if your telephone number is incorrect or outdated? Well, you can update it, of course!
- Follow the same instructions as above to access Facebook’s Security Settings and tap ‘Edit’ next to 2FA. Next to ‘Your security method’ tap ‘Manage.’
- Then, click ‘Use a different number’ from the dropdown menu.
- Click ‘Add Phone Number’ then, ‘Continue.’
- Type in your new phone number and tap ‘Continue.’
The new phone number should appear. But, if it doesn’t or your receive an error code, you can turn off 2FA then turn it on again. Doing this will let you input a brand new phone number.
Frequently Asked Questions
Securing your Facebook account is all too important these days. We’ve included this section to answer more of your questions.
Do I need 2FA?
2FA or a similar alternative is highly recommended, especially for Facebook. The social media site has access to a lot of your personal information you probably haven’t thought about, for one thing. You don’t want a hacker having that information. Things like your location, identity, and even payment information are all stored on Facebook.
If your account gets hacked, Facebook may take it upon themselves to completely deactivate your account. This type of action means you won’t get your account back, and you’ll lose all of your pictures, friends, and meaningful memories.
What can I do if I can’t receive the 2FA code?
Assuming you don’t have a backup option established and you no longer have access to the phone number on file, you’ll need to use an alternative method to log in. Your best option will be using a recognized device to get your security codes in the Settings.
If you don’t have a recognized device with you, don’t have your security codes, and don’t have access to one of the forms of contact listed on your account, use the ‘Trouble signing in’ option from the login page.
I can’t turn off 2FA on Facebook. What’s happening?
There are a few possible reasons why Facebook won’t let you turn off 2FA. If you have specific apps connected to Facebook, one may prevent you from turning off the feature because it’s required for security purposes. Try removing any linked work or school apps, then follow the instructions again. If you are receiving an error, try another web browser to turn the security feature off because it could be an issue with the browser itself. Assuming you’re using the correct password when logging in, you may need to contact Facebook support for more help. Generally, Facebook gives you no issues turning off this feature, so if you are running into a problem, it’s likely account-specific, which is why you’ll need the support team to help you out.
What do I do if someone else logged in and turned on 2FA on my account?
If you’ve already experienced an attack and the hacker turned on 2FA, you can’t log in until the matter gets resolved. Fortunately, Facebook is prepared to help. Visit this webpage to recover and regain access to your account so that you can turn off or manage 2FA.
Do I need a verification code to turn off 2FA?
No, but you do need one to turn it back on. You will need your password to access the security settings, but you will not need a text message verification code to turn it off.
