What is the difference between a captcha and reCAPTCHA?
-
“Captcha” is the general term for a test to tell humans and bots apart.

[cite: 43] ThinkCaptcha uses Google’s secure and user-friendly reCAPTCHA v2. [cite: 44]
-
Does this plugin slow down my site?
-
No. The plugin is lightweight, and the Google reCAPTCHA script is loaded asynchronously using WordPress best practices, meaning it doesn’t block your page from loading. [cite: 45] It only loads on pages where the captcha is active. [cite: 46]
