To implement Google reCAPTCHA on your website, follow these general steps:
Sign up for reCAPTCHA: Go to the reCAPTCHA website (https://www.google.com/recaptcha) and sign in with your Google account. You will need to register your website and obtain API keys.
Choose reCAPTCHA type: Decide whether you want to use reCAPTCHA v2 or reCAPTCHA v3. reCAPTCHA v2 provides the traditional "I'm not a robot" checkbox, while reCAPTCHA v3 is a background verification system that assigns a score to user interactions.
Obtain API keys: Once you have registered your website, you will receive a site key and a secret key. These keys will be used to integrate reCAPTCHA into your website.
Add reCAPTCHA script to your HTML: Insert the reCAPTCHA script tag into the <head> section of your HTML file. This script is provided by Google and loads the reCAPTCHA functionality on your web page.
Add reCAPTCHA widget: Place the reCAPTCHA widget where you want it to appear on your website. For reCAPTCHA v2, this is typically a checkbox element. For reCAPTCHA v3, you will need to add a script to initiate the verification process.
Verify the response: When a user submits a form or performs an action, you need to verify the reCAPTCHA response on your server-side code. Send the response token to Google's reCAPTCHA API for verification using your secret key.
Handle the verification response: After submitting the reCAPTCHA response to Google, you will receive a verification response. Based on this response, you can determine if the user is a human or a bot and proceed accordingly.
The implementation details can vary depending on your programming language and framework. Google provides detailed documentation and code examples for various platforms, which you can refer to for specific implementation steps.
Remember to handle the verification on the server-side, as client-side verification can be bypassed by malicious users.
