To get reCAPTCHA keys from Google, follow these steps

Steps to Get reCAPTCHA v2/v3 Keys:

1. Go to the reCAPTCHA Admin Console:
   👉 https://www.google.com/recaptcha/admin
   (Sign in with your Google account if prompted.)
2. Register a New Site:
   • Click “+” (Create) or “Register a new site”.
   • Fill in the required details:
     • Label: A name for your site (e.g., “My Website”).
     • reCAPTCHA type: Choose between:
       • reCAPTCHA v2 (“I’m not a robot” Checkbox or Invisible reCAPTCHA)
       • reCAPTCHA v3 (Returns a score, no user interaction)
     • Domains: Add your website domain (e.g., example.com).
       (For testing, you can use localhost or 127.0.0.1 if working locally.)
   • Accept the reCAPTCHA Terms of Service.
   • Click Submit.
3. Get Your Keys:
   • After submission, you’ll see:
     • Site Key (Public key, used in your HTML/JS)
     • Secret Key (Private key, used for server-side verification)
   • Copy both keys and store them securely.

Important Notes:

• Keep Secret Key Private: Never expose it in client-side code.
• Restrict Keys (Optional): In the admin panel, you can restrict keys to specific domains/IPs.
• Testing Locally: Use localhost as a domain if testing on your PC.

Where to Use the Keys?

• Frontend (HTML/JS): Include the Site Key in your reCAPTCHA widget.
• Backend (PHP/Node.js/Python/etc.): Use the Secret Key to verify user responses.
