Google’s reCAPTCHA is a free, widely used tool that helps websites detect and block bots. Whether you’re running a blog, eCommerce site, or business landing page, adding reCAPTCHA strengthens your site’s security.
reCAPTCHA is a security service by Google that distinguishes humans from automated bots. It protects forms, logins, and interactions from being misused.
Types of reCAPTCHA
- re CAPTCHA v2 – User clicks “I’m not a robot” or completes image challenges
- Invisible reCAPTCHA – Works silently in the background, prompts challenge only when needed
- re CAPTCHA v3 – Calculates a score based on user behavior without interruptions
