+Usually you'll need a 2FA URL, so you just have to use the URL generator:

+

+```php

+    $google2fa->getQRCodeUrl($companyName, $companyEmail, $secretKey)

+```

+Here's an example using Simple QrCode:

+

+```php

+<div class="visible-print text-center">

+    {!! QrCode::size(100)->generate($google2fa->getQRCodeUrl($companyName, $companyEmail, $secretKey)); !!}

+    <p>Scan me to return to the original page.</p>
