Google reCAPTCHA is a free service developed by Google to protect websites from spam, bots, and abusive activities. It uses advanced risk analysis, machine learning, and user interaction challenges—such as selecting images or solving puzzles—to distinguish human users from automated programs. Available in versions like reCAPTCHA v2 (with checkboxes or image selection) and v3 (an invisible, score-based system), it enhances security while maintaining a seamless experience for legitimate visitors, ultimately safeguarding online forms, logins, and content submissions.
