Enable Default Captchas

We strongly recommend using reCAPTCHA v3 or hCaptcha® instead. These captcha options include enhanced protection against automated captcha solvers.

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. WHMCS’s default captcha option displays an image with six characters on a blue striped background. Your customers must enter this six-character code correctly to proceed.

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

For more information, see Captcha Protection.
