The Facebook login code is generated every time someone tries to access your account on a secondary device. The feature works in conjunction with two-factor verification, reducing the chances of intruders breaking into your profile on the social network.

There is also the possibility of generating new codes without having the cell phone in hand. Learn below what is the Facebook login code, how to generate access codes and what to do when the numerical codes are not sent to your smartphone.

What is Facebook login code?

The Facebook login code is an extra alternative to increase the security of your account on the social network. It works off of the two-factor authentication feature, which is when the platform asks for a secondary confirmation to release account access.

Anytime you access your Facebook account on a device other than your primary device, a login code will be required to complete the action. This code can be a physical security key, a text message (SMS), or a third-party authentication app like Google Authenticator.

In addition to the code used in two-factor verification, Facebook allows you to generate other security codes for you to use when your cell phone is not nearby. It is possible to create 10 codes at a time, which can then be used for each login to your Facebook account.

How to get Facebook login code

The first thing you need to do is enable two-factor authentication on Facebook and select one of the methods to receive the login code from Facebook. Sign in options include:

  • Use a six-digit code sent by SMS;
  • Use a security code in your code generator;
  • Tap your security key on a compatible device;
  • Use a security code from a third-party app (Google Authenticator, for example) associated with your Facebook account.

The Facebook login code is created the moment someone tries to access your account on a mobile phone or PC that is not your primary device. So, to get the code, simply open Facebook on the secondary device and, when prompted, verify it via SMS or an authenticating ID app.

Remember that the Facebook login code is unique and is valid for a short period of time. If the code has not been used in a few minutes, you will need to log in again to receive a new code.

How to Generate Facebook Login Codes

To get Facebook login codes, make sure you enable two-step authentication. The procedure can be done either on the Facebook website through a browser, or on the social network application for Android and iPhone (iOS) mobile phones.

Once two-factor verification is enabled, now it's just a matter of getting the Facebook login codes. To do this, follow the steps in the tutorial below. In this example, we're using the web version of Facebook, but you can also generate the codes in the app.

  1. Go to "facebook.com" or open the mobile app to log in to your account;
  2. In the upper left corner, click on your profile picture;
  3. Go to “Settings and Privacy” and then to “Settings”;
  4. In the menu on the left side, click on “Security and login”;
  5. Under “Two-Factor Authentication”, click “Use Two-Factor Authentication”;
  6. Under “Recovery Codes”, click “Setup”;
  7. Click "Get Codes". If you already have generated codes, click on “Show codes”;
  8. Check out the list of Facebook login codes.

Facebook generates 10 login codes each time you access this feature in your account settings. That is, you can repeat this process every time you want to generate new codes, since they expire after being used. It is recommended to write down all the codes or select the “Download” option to download a text file with the numbers.

Facebook login code is not enough: what to do?

If two-factor authentication is already enabled on your Facebook and you don't receive the code via SMS (if you choose this option), your phone number may have problems with your carrier. It is also worth checking if the cell phone chip is well seated in the device, if it is a physical chip and not an eSIM.

Now, if you haven't changed carriers and the Facebook login code still isn't coming through, try the following:

  • Contact your mobile operator to verify that you are sending the SMS to the correct number;
  • remove signatures at the end of text messages (SMS) that may prevent Facebook from receiving these messages;
  • Try sending an SMS to “On” or “Fb” (without quotes) to the number 32665;
  • Please allow 24 hours if there is a delivery delay.

Another alternative is to change the two-factor authentication method in Facebook's privacy settings. Then just choose a third-party app. Or, write down the 10 login codes generated by Facebook and use them until they run out.
