About this project
What does Authentication add?
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.
