Website security is paramount in recent days, and Google reCAPTCHA serves as a frontline defense against spam and abuse. Integral to this system is the reCAPTCHA Site Key, a unique identifier that ensures interactions on a website are human-driven. Understanding how to locate this key is essential for website administrators and developers alike.

What is a reCAPTCHA Site Key

A reCAPTCHA Site Key is a unique identifier used by Google reCAPTCHA to verify user interactions on a website. It is part of the reCAPTCHA service that helps protect websites from spam and abuse by ensuring that the interaction is being performed by a human rather than a bot.

How to Find Website's Google reCAPTCHA Site Key

  1. Visit the Target Website:
    Open the website where you want to find the reCAPTCHA Site Key.

  2. View Page Source:

    • Right-click on the webpage and select "View Page Source" or use the shortcut Ctrl+U (Windows) or Command+Option+U (Mac).
    • Alternatively, you can press F12 to open the developer tools and then select the "Elements" tab.
  3. Search for reCAPTCHA Code:

    • In the source code page, press Ctrl+F (Windows) or Command+F (Mac) to open the search box.
    • Type data-sitekey in the search box.
  4. Find the Site Key:

    • You will see a code snippet similar to the following:
      <div class="g-recaptcha" data-sitekey="YOUR_SITE_KEY"></div>
    • The value of the data-sitekey attribute is the reCAPTCHA Site Key for that website.


Suppose you find the following code snippet in the source code of a website:

<div class="g-recaptcha" data-sitekey="6Lc_aX0UAAAAABxX0X0X0X0X0X0X0X0X0X0X0"></div>

In this case, 6Lc_aX0UAAAAABxX0X0X0X0X0X0X0X0X0X0 is the Google reCAPTCHA Site Key for that website.

By following these steps, you can easily find the Google reCAPTCHA Site Key for any website. Please note that using other Site Key might involve legal and privacy issues, so make sure to use this information legally and ethically.
