Which CAPTCHA should I choose?

Does this plugin slow down my site?
No. Assets (CSS/JS) are conditionally loaded only on pages where a Contact Form 7 form is present. We prioritize performance and lightweight code.
Can I use multiple CAPTCHAs per page?
Yes! Each Contact Form 7 form can have its own independent CAPTCHA configuration.
does it work on mobile devices?
Absolutely! The CAPTCHA is fully responsive and works perfectly on all devices including smartphones and tablets.
Is it accessible for people with disabilities?
Yes! The plugin includes proper ARIA labels, keyboard navigation, and screen reader compatibility following WCAG 2.1 guidelines.
Can I customize the appearance?
Yes! Choose from three built-in themes (Default, Minimal, Modern) or add custom CSS for further customization.
What is the BotShield CAPTCHA shortcode?
The required shortcode is [captcha* captcha-answer]. This tag ensures that the user completes the CAPTCHA before submitting the form.
Can I use the shortcode for Google reCAPTCHA or Turnstile?
Yes! The same [captcha* captcha-answer] shortcode works for all types. The plugin automatically renders the correct challenge (reCAPTCHA, Turnstile, or Built-in) based on your settings.
How do I make the shortcode optional?
To make the CAPTCHA optional (not recommended), use the tag without the asterisk: [captcha captcha-answer].
