ThinkCaptcha – Captcha for Login, Register and WooCommerce

ThinkCaptcha adds a simple, effective captcha to the WordPress and WooCommerce forms that get attacked the most, so you can stop spam registrations, brute-force login attempts, and junk submissions.

It uses Google’s familiar “I’m not a robot” checkbox (reCAPTCHA v2) and turns it on with a single toggle — no coding needed. The captcha only loads on the pages that actually use it, so it stays light on performance.
