Plugin UltraAuth

UltraAuth, Lightweight Authentication for Minecraft Servers

UltraAuth is a Java authentication plugin for Bukkit based Minecraft servers, designed to protect accounts on offline mode networks without adding unnecessary performance overhead. Players use simple commands such as /register, /login, and password reset tools before accessing gameplay.

Unauthenticated players can be teleported to a configured spawn and restricted from moving, walking, or breaking blocks. The plugin uses potion effects to reduce event processing, supports UUID based accounts, and encrypts stored passwords. At BoxToPlay, we see UltraAuth as a straightforward security layer for servers running Minecraft 1.8.
