## Descripción

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.
