About this Mod

Authentication

This plugin allows the authentication of Minecraft players in web applications via Nginx auth_request. It is a single puzzle piece in this ecosystem to secure and lock down your Minecraft server related websites such as maps or analytics pages. You can use this plugin as a standalone and let the web application do the access control but only a few of such applications exists so you will probably want the next piece
for Authorization

Due to the need of external software and multiple ports. You will most likely not be able to use this on any Minecraft hosting services and need to have a proper server such as a cloud vps or a dedicated server.
Keep in mind that authentication is an advanced topic and you are expected to have basic understanding of Nginx and networks to be able to succesfully use this plugin.

See the GitHub repository readme for more details and installation instructions.

Frequently Asked Questions

Authentication server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.1). You can switch loaders with one click in the panel.

Is Authentication compatible with fabric and paper and spigot?

Authentication officially supports fabric, paper, spigot for Minecraft 26.1, 1.21.11, 1.21.10. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Authentication – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Authentication consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
