# SCaptcha

> Proof-of-Work bot protection for WoltLab Suite 6.2. The standard verification runs between the visitor's browser and the operator's own WoltLab installation.

SCaptcha 2.3.0 uses a fresh, cryptographically random 32-byte salt for every 60-second challenge. Sentinel, browser checks, proxy intelligence, analytics, and Under-Attack mode are separate, configuration-dependent features. Optional services must not be described as local or cookie-free.
