$seed = random_bytes(20);
$auth = new GoogleAuth($seed);
$auth->makeQRCode(null, 'php://output', '[e-mail]', 'Issuer', 'Label');

Validate two-factor code

<?php
use ParagonIE\MultiFactor\OneTime;
use ParagonIE\MultiFactor\OTP\TOTP;

// You can use TOTP or HOTP
$otp = new OneTime($seed, new TOTP());

if (\password_verify($_POST['password'], $storedHash)) {
    if ($otp->validateCode($_POST['2facode'], time())) {
        // Login successful    
    }
