How can I create a Member Page custom sign up with just facebook?

Could anybody help me? I would like to create a custom sing up with just Facebook sing in. However, there is a page where you can sign up with Facebook and any other email address on wix. And I don’t want my Members to sing up with any other email. So I want a solution for custom sing up. I looked for codes on the internet, but I couldn’t find any working one. I have created a Facebook button with “developers. facebook. com” I have problem with " Valid OAuth Redirect URIs". I tried many links but nothing worked. Could anybody help me, what should I write on “Valid OAuth Redirect URIs” box?

I put a code inside a HTML box on my wix page. It’s shows a facebook button. If you need the code for the help, I can send you on email, because this forum not allowed me to put the code here.

I found out how to share the code with you.

There is a better way, how to share a CODE with other forum-user.
Please use CODE-Tags… like this one here…

  (function(d, s, id){

     if (d.getElementById(id)) {return;}
     js = d.createElement(s); js.id = id;
     js.src = "https://connect.facebook.net/en_US/sdk.js";
     fjs.parentNode.insertBefore(js, fjs);
   }(document, 'script', 'facebook-jssdk'));

</script>
