Creating a Google reCAPTCHA for your website involves a few steps. reCAPTCHA is a service provided by Google to protect websites from spam and abuse by verifying that the user is not a robot.
-
Sign Up for reCAPTCHA:
Go to the reCAPTCHA website and sign in with your Google account. If you don’t have one, you’ll need to create one.
-
Register Your Website:
After logging in, click the “+ (plus)” icon at the top right to add a new site, then Fill in the required information about your website.
-
Choose reCAPTCHA Type:
Google reCAPTCHA offers two types:
- reCAPTCHA v2 “I’m not a robot” Checkbox: This is the traditional CAPTCHA with a checkbox.
- reCAPTCHA v2 “Invisible” CAPTCHA: This is a more user-friendly version that runs in the background and only requires interaction if Google suspects suspicious activity.
Choose the type that suits your needs. The setup process is similar for both.
-
Domain Verification:
You’ll need to verify your website’s domain to use reCAPTCHA. Follow the instructions provided on the reCAPTCHA admin console for domain verification.
-
Get API Keys:
Once your domain is verified, you’ll receive API keys for your reCAPTCHA. There are two keys:
- Site Key: This key is used on the frontend (your website) to display the reCAPTCHA widget.
- Secret Key: This key is used on the backend (your server) to verify the user’s response.
