ChromAuth is an enterprise-grade, lightweight authentication framework tailored explicitly for Paper 1.21.11 infrastructure. Designed from the ground up to replace bloated, legacy login managers, ChromAuth protects servers from identity theft, unauthorized account access, and malicious bot vectors while maintaining an incredibly light system footprint. 💻✨
🌟 Key Features:
Cryptographically Secure Data Footprint: Say goodbye to raw text vulnerabilities. ChromAuth protects your community's data natively using BCrypt with salted keys, matching modern web standard security patterns. 🛡️🔑
Total Player Isolation: Unauthenticated sessions are instantly locked. Impact processes automatically restrict movement vectors, chat streams, physical item interactions, command injections, and incoming entity damage. 🥶🙅♂️
Intelligent IP-Session Caching: Minimize player login fatigue. If a player drops connection due to a client crash or a quick server reboot, they can rejoin fluidly without typing a password, provided they reconnect from the exact same network footprint within the admin-defined time frame. 🔄🔌
Complete Formatting Autonomy: Tailor every user interaction via a dedicated messages.yml engine with built-in color-code processing. 🎨💬
Anti-Camp Dynamic Auto-Kicker: Keep your player slots clear. A background scheduling framework automatically purges clients that fail to pass authentication walls within a configurable timeframe. ⏱️👢
