title: How Google's reCAPTCHA v3 works
body: <p>Google has rolled out <a href="https://developers.google.com/recaptcha/docs/v3" rel="nofollow noreferrer">reCAPTCHA v3</a>. It does away with all the user friction. I wish to use it to secure my site. However, I am unsure about how this is going to protect my site. What if a hacker spams the URLs on my site with an external tool without using the interface I provide? How is reCAPTCHA v3 going to stop that?</p>
