Title: Adding CAPTCHA to a Drupal 8 Webform

Introduction:

CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a common method used to prevent automated bots from submitting forms on websites. In Drupal 8, integrating a CAPTCHA into a Webform can help enhance security and ensure that form submissions are made by real users. In this guide, we will walk you through the process of adding a CAPTCHA to a Drupal 8 Webform.

Step 1: Install Required Modules

Before we begin, ensure that you have the following modules installed and enabled on your Drupal 8 website:

1. Webform: This module allows you to create and manage webforms on your site easily.

2. reCAPTCHA: This module integrates the Google reCAPTCHA service with Drupal forms, including Webforms.

Step 2: Set Up Google reCAPTCHA

To use the Google reCAPTCHA service, you need to register your website with Google and obtain the necessary API keys. Here's how you can do it:

1. Go to the Google reCAPTCHA website (https://www.google.com/recaptcha) and sign in with your Google account.

2. Click on the "My reCAPTCHA" button and then click on the "+ Register a new site" button.

3. Fill in the required details for your website, such as the label and domains where the CAPTCHA will be used.

4. Choose the reCAPTCHA version (v2 "I'm not a robot" checkbox or v3 invisible CAPTCHA) based on your preference and website requirements.

5. Add the domain(s) where you want to use the CAPTCHA. Make sure to include both the development and production domains if necessary.

6. Agree to the terms of service and click on the "Submit" button to create your reCAPTCHA site.

After completing the registration, you will receive two keys: a Site key and a Secret key.

Step 3: Configure reCAPTCHA in Drupal 8

Now that you have your API keys, it's time to configure the reCAPTCHA module in Drupal:

1. Navigate to "Configuration" > "Webforms" > "Settings" > "reCAPTCHA" (admin/config/services/recaptcha).

2. Enter the Site key and Secret key you obtained from the reCAPTCHA website into the respective fields.

3. Choose the reCAPTCHA version you want to use (v2 or v3) from the drop-down menu.

4. Select the Webform elements that should be protected with CAPTCHA. Usually, this includes the form's submit button.

5. Set the CAPTCHA difficulty level to either "Easy" (for v2) or "Hard" (for v3) based on your security requirements and user experience preferences.

6. Save the configuration to apply the changes.

Step 4: Add CAPTCHA to a Webform

With the reCAPTCHA module configured, you can now add the CAPTCHA to your Webform:

1. Go to "Structure" > "Webforms" (admin/structure/webform) and choose the desired Webform for which you want to add the CAPTCHA.

2. Click on the "Form" tab to open the Webform builder.

3. Drag and drop the "CAPTCHA" element from the "Add elements" section onto your form.

4. Configure the CAPTCHA element settings, such as the label and any specific CAPTCHA instructions.

5. Save the Webform to apply the changes.

Step 5: Test the CAPTCHA

Before making the Webform live, it's crucial to test the CAPTCHA to ensure it's working correctly. Open the Webform in a browser and try submitting it to verify if the CAPTCHA is functioning as expected.

Conclusion:

By following the steps outlined in this guide, you have successfully added a CAPTCHA to your Drupal 8 Webform. This additional layer of security will help protect your forms from spam and bot submissions, ensuring that genuine users can interact with your website seamlessly.
