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.

Features

✔ Full Authentication Lockdown

Unauthenticated players cannot:

• Move or rotate their aim
• Use commands (except /register, /login, /verify, /auth)
• Break/place blocks, interact, drop/pickup items, or chat

Optional protections:

• Darkness effect while unauthenticated
• Auth timeout with boss bar countdown
• Title prompts during auth
• Optional success title after login

✔ Configurable Locations

• Auth Location: where players spawn until they authenticate /auth setauth
• Spawn Location: where first‑time players go after their first successful auth /auth setspawn

✔ Security & Anti‑Abuse Tools

• IP‑based registration limits
• Join rate limiting
• Brute‑force protection with lockout

✔ Admin Settings

• In‑game settings GUI: /auth settings
• Reload config: /auth reload

✔ Fully Configurable

Every major feature can be toggled and tuned in config.yml.
