Share Code to get 2FA code like 2fa.live

2FA, also known as 2-step verification, helps you to secure your Facebook account more. Once you have entered your Facebook login password, you will need to provide an additional random 6-digit code provided by the 2FA code generator. However, if you don’t have a phone, you can still make your own 2FA code site. Below is the source Code to get the 2FA code like 2fa.live. Proceed as follows:

Create files 2fa.php with content:

<?php 

require_once 'GoogleAuthenticator.php';

if (isset($_GET['key']))
{
    $key = trim($_GET['key']);
    $ga = new PHPGangsta_GoogleAuthenticator();
    $code = $ga->getCode($key);
    $list = [
    "key"=>$key,
    "code"=>$code
    ];
    $daucatmoi = json_encode($list, JSON_PRETTY_PRINT);
    $memay = json_decode($daucatmoi, true);
    echo $memay['code'];
}
?>

Upload to Hosting. So we have the same source code for 2FA as 2fa.live.

Activate 2FA on Facebook to get secret code

You access the link to enable 2FA for the application at: https://www.facebook.com/security/2fac/settings

Navigate to Authenticator -> Setup

On the screen will display a QR code and a secret code, you need to copy this secret code to notepad and save it on your computer. This secret code is used to get Facebook’s 2FA code
