Creating a CAPTCHA in Drupal 8 is essential to protect your website from spam and automated bots. A CAPTCHA is a challenge-response test used to determine whether the user is human or a machine. In this guide, I'll provide you with step-by-step instructions to add a CAPTCHA to your Drupal 8 forms using the "reCAPTCHA" module, which is widely used and well-maintained.

2. Go to Extend (Modules) by navigating to "Extend" from the top admin menu.
3. Search for "reCAPTCHA" in the module list or browse to find it.
4. Click the checkbox next to "reCAPTCHA" to select it for installation.
5. Click the "Install" button at the bottom of the page.
6. After installation, click the "Enable" button to enable the module.
2. Click the "My reCAPTCHA" button at the top-right corner and log in with your Google account.

4. Agree to the reCAPTCHA terms of service and click "Submit."
1. In your Drupal admin panel, navigate to Configuration > People > CAPTCHA (admin/config/people/captcha).
2. Under the "CAPTCHA module" drop-down, select "reCAPTCHA" as the CAPTCHA module to use.
3. Scroll down to the "reCAPTCHA settings" section and enter the obtained Site key and Secret key in their respective fields.

2. Click on the "Form display" or "Manage form display" tab, depending on your Drupal version.
3. Locate the field that represents the form element where you want the CAPTCHA to appear (e.g., "CAPTCHA" for the contact form).
4. Drag and drop the "CAPTCHA" field into the form layout, positioning it where you want the CAPTCHA to appear.
5. Save the form display settings.
1. Visit the form on the frontend of your Drupal website where you added the CAPTCHA (e.g., Contact page, Registration page).
2. Fill out the form and submit it to see the CAPTCHA in action.
