Secure Your Facebook account with two-factor authentication

 You can increase the security of your account by using two-factor authentication. When you enter your Facebook password, Facebook will give you an OTP code (message) to your phone. Only after entering the code will you be able to access Facebook.

To use this feature, go to your Facebook settings and select Security & Login. It has a Two Factor Authentication option, so go to Use Two Factor Authentication.

There is now an option to use Google Authenticator or SMS. In that case, we recommend that you select the SMS alternative.

Because it is simpler and more stable. Put your phone number there now. The OTP code is then sent to your device. And then enter the same code into the box there. After that, two-factor authentication is allowed on your Facebook account.

When logging in to Facebook on any new device, you must now enter the OTP code. Even if anyone knows your secret, they would be unable to access Facebook without the OTP code.
