Captcha upon login

[bigs15]

Hey guys i am trying to acc captcha protection for 3.8.7 vbulletian forum. I tried very much but failed
I tried this code in header login area.
The Standard Challenge and Non-JavaScript API,

<script type="text/javascript"
     src="http://www.google.com/recaptcha/api/challenge?k=your_public_key">
  </script>
  <noscript>
     <iframe src="http://www.google.com/recaptcha/api/noscript?k=your_public_key"
         height="300" width="500" frameborder="0"></iframe><br>
     <textarea name="recaptcha_challenge_field" rows="3" cols="40">
     </textarea>
     <input type="hidden" name="recaptcha_response_field"
         value="manual_challenge">
  </noscript

>

It show the recaptcha box.But forum looks ugly so i tried regex method of recaptcha buts not working.

The reCAPTCHA AJAX API

<script type="text/javascript" src="http://www.google.com/recaptcha/api/js/recaptcha_ajax.js"></script>

      <!-- Wrapping the Recaptcha create method in a javascript function -->
      <script type="text/javascript">
         function showRecaptcha(element) {
           Recaptcha.create("your_public_key", element, {
             theme: "red",
             callback: Recaptcha.focus_response_field});
         }
      </script>

    <div id="recaptcha_div"></div>

      <input type="button" value="Show reCAPTCHA" onclick="showRecaptcha('recaptcha_div');"></input>

Doc: https://developers.google.com/recaptcha/docs/display

Captch and reCaptcha are constantly being bypassed by bots these days so maybe install this https://vborg.vbsupport.ru/showthread.php?t=254671 if thats the way you want to go, i have to tell you though that i've had the Q&A human verification thats built in to vbulletin in use since starting my forums a good few years ago, i have 10 questions that i change every two years and in all that time i've only had to ban 125 spammers all of which have been organic and not automated bots

captcha during login also needed bro.Its a new technque.My foru not getting spa getting brute force atm.ack.Soe one help me that will be nice.

Brute force on login????? your forum is set to lock them out after 5 wrong attempts for 15 minutes!, in General Settings here's the documentation for it:
Use Login "Strikes" System
Setting this to 'yes' will enable a system that tracks a user's (with a specific IP address) login attempts. After 5 incorrect login attempts the account is locked from that IP address for 15 minutes. This is to prevent bruteforce login attacks

While ip banning "works" is not reliable.. Theres millions of proxies out there so brute forcing that would be very easy.. Not a good option. Captcha on login is way better. Dont know why VB does NOT implement it. Specially after all the requests made.
