ULTIMATE AUTH
UltimateAuth is a powerful, modern authentication system for offline-mode Minecraft servers. Packed with security features, full spawn control, IP-based registration limits, movement lockdown, blindness effects, and a polished user experience.
UltimateAuth is a secure, performance‑first authentication plugin for offline‑mode Paper servers. It delivers a clean login/register experience while locking down unauthenticated players to prevent impersonation, grief, and unauthorized access.
Whether you run a small SMP or a large network, UltimateAuth ensures every player verifies before they can move, interact, or play — and everything is fully configurable.
