WordPress captcha plugins protect forms, login pages, comment sections, and registration flows from automated bot submissions and credential-stuffing attacks. They implement verification mechanisms including Google reCAPTCHA v2 and v3, hCaptcha, Cloudflare Turnstile, and custom math or honeypot challenges that distinguish human users from automated scripts. Site owners, developers, and security teams use captcha plugins to reduce spam form submissions, block fake account registrations, and protect the wp-login.php endpoint without requiring users to solve frustrating visual puzzles. Modern invisible captcha options provided by WordPress captcha plugins balance strong bot protection with a frictionless user experience that does not penalise legitimate visitors.
