Plugin Packet Auth

Packet Auth

Packet Auth is a Minecraft plugin designed to add an authorization layer to servers running without online mode. It verifies connecting players through a token exchanged by a custom plugin message, helping prevent unauthorized access while keeping the login process lightweight. The matching client mod is required for this verification to work.

Built for Java Edition, it supports Bukkit based platforms including Paper, Spigot, Purpur and Folia, as well as BungeeCord, Velocity and Waterfall networks. Owners can customize messages, checks, token generation and storage, with file or MySQL options. At BoxToPlay, we recommend it for administrators seeking practical, configurable protection.
