This is essential

If you want to use hCaptcha for blocking comment spam, this is the way to do it. The plugin indicates integrations with various contact form plugins also. Some of these contact forms (notably including WPForms Lite) have their own hCaptcha functionality built in and don’t require this plugin. So if you’re not allowing comments anyway, or if you’re blocking comment spam in some other way, check first whether you need this plugin.

Definitely use this in preference to any reCAPTCHA plugin, to enhance visitor privacy.
