설명
Mathlock Guard protects your site’s public-facing content behind a lightweight math verification challenge. Visitors must correctly answer a simple arithmetic question before accessing your pages, providing an accessible, low-friction alternative to traditional CAPTCHA systems. Site administrators and the login page remain fully accessible at all times, ensuring uninterrupted site management, while all other visitors, including logged-in users such as editors, authors, and subscribers, are required to pass the verification screen.
