Facebook uses security codes as an extra layer of protection for your account. A security code may be required when you log in from a new device, change your password, enable two-factor authentication, or take other actions to help secure your account.
What is the Facebook security code?
The Facebook security code is a 6-digit code that is randomly generated and sent to your confirmed phone number or email address on file. This provides a second form of identity verification beyond just your password when performing important account actions. The security code is also sometimes referred to as a 2-factor authentication code or 2FA code.
When will I need a security code?
Some of the most common situations when Facebook will require a security code include:
- Logging into your account from a new device, like a new phone or computer
- Changing your account password
- Enabling or disabling two-factor authentication
- Adding a new login method like a security key
- Making payments or financial transactions
- Recovering your account if you get locked out
Essentially any major account changes or sensitive actions will require an extra security check via the code.
How do I get the security code from Facebook?
When a security code is needed, Facebook will send it to you via either text message/SMS or email. The method you’ll receive it through depends on the contact information you have set up with your account.
To get the code via text:
- Make sure your mobile phone number is confirmed in your Facebook account settings
- When prompted, choose to receive the code via text message
- Facebook will text you a 6-digit numerical code
- Enter this code within the designated time frame to complete the action
To get the code via email:
- Make sure you have a confirmed email attached to your Facebook account
- When prompted, choose to receive the code via email
- Check your email inbox for a message from the Facebook security team
- Open the email and copy the 6-digit code
- Paste the code into Facebook within the time limit
How long are security codes valid for?
Facebook security codes expire after a short period of time, usually 10-15 minutes. This ensures that even if the code is somehow obtained by someone else, it can’t be used to gain access after it has expired.
If your code expires before you use it, you will have to request a new code from Facebook and repeat the verification process.
What if I’m not getting the security code?
If you are not receiving a security code from Facebook when prompted, here are some troubleshooting tips:
- Double check that your contact info is up-to-date in your account settings. Make sure your email and mobile number are confirmed.
- Check your spam folder – sometimes the code email ends up routed there.
- Make sure your phone has reception and can receive texts. Facebook codes won’t come through if you have poor signal.
- Try toggling your text messaging options and resending the code. Choose email if text doesn’t work.
- As a last resort, you can go through Facebook’s account recovery process to regain access if you cannot obtain the code.
How do I change the delivery method for security codes?
If you would prefer to receive your Facebook security codes through email rather than text, or vice versa, you can change the delivery method in your account settings:
- Go to your Facebook account settings
- Select the “Security and Login” tab
- Under the Two-Factor Authentication heading, click “Edit”
- Toggle your preferred two-factor authentication delivery method to text message or email
- Be sure to click “Save Changes” at the bottom
Now your security codes will be sent to you through your preferred contact method moving forward.
Can I set up backup codes?
In addition to text and email delivery, Facebook gives you the option to generate one-time backup codes. These are 8-digit codes that can each only be used once, but act as an alternative to the regular 6-digit security code.
To set up backup codes:
- Go to your Facebook Security and Login settings
- Under Two-Factor Authentication, click “Edit”
- Click “Generate Codes” under the Backup Codes section
- Facebook will generate and display several 8-digit backup codes
- Write these codes down and store them somewhere safe in case you need them
If you ever lose access to your normal two-factor authentication method, you can enter one of your backup codes instead. Just make sure to only use each code once.
Can I turn off two-factor authentication?
If you don’t want to continue using two-factor authentication with Facebook, you can disable it:
- Go to your Facebook Security and Login settings
- Under Two-Factor Authentication, click “Edit”
- Toggle the Enable/Disable switch to “Disable”
- Confirm you want to turn off two-factor authentication
Once disabled, you will no longer be prompted for a security code when accessing your account.
Conclusion
Facebook’s two-factor authentication via security codes helps prevent unauthorized access to your account. To use it, make sure your phone and/or email is confirmed on your Facebook account. When prompted, select your delivery method for the 6 or 8-digit code and enter it within the designated timeframe. Backup codes provide an alternative access option if your primary code method is unavailable. You can disable two-factor authentication if you no longer wish to use it.
