Captchas help you prevent bots from performing activities like placing orders, creating accounts or support tickets, using contact forms, searching for domains, or logging in to your Client Area or Admin Area. hCaptcha offers enhanced protection from automated captcha solvers using either a checkbox-based captcha (hCaptcha) or an invisible captcha (Invisible hCaptcha).

You can enable and configure several types of captchas in the Security tab at Configuration () > System Settings > General Settings.
