AuthSession API Coming soon ​

This feature is currently unavailable. You can view a draft of the custom Mojang AuthSession API here: https://github.com/minekube/mojang-multiauth. For support requests, join our Discord community. https://minekube.com/discord

This page explains the planned Connect AuthSession API and what it does not support today.

Requirements

-> Requires a public IP address

-> Only useful if you want to use Connect with online mode players.

Current Status ​

The AuthSession API is not available in production yet. The example commands on this page are placeholders and should not be used as working setup instructions.

Today, Connect supports online-mode players through connectors that integrate with Connect's current auth/session handling, such as standard Gate with Connect enabled or the Connect Java Plugin on supported platforms.

Gate Lite behind Connect is different: Lite mode is a thin Java protocol reverse proxy. It forwards ping and player authentication to the selected backend route instead of acting as a full proxy that can translate Connect's edge-authenticated session into a backend online-mode login.

Because AuthSession and Connect passthrough support are not available yet, the following topology is not supported by Gate Lite configuration alone:

Connect -> Gate Lite -> Online Mode Backend

Use standard Gate with Connect enabled or the Connect Java Plugin when you need online-mode players through Connect today. Use Gate Lite behind Connect only when the backend auth model is compatible with a thin reverse-proxy hop.

How it Works ​

The planned Connect AuthSession API is an adaptation of the Mojang AuthSession API. It is intended to securely authenticate online-mode players from the Connect Network to your server/proxy.

The API distributes Mojang Sessionserver's "hasJoined" requests from online mode servers/proxies possibly behind Minekube Connect, Minehut Network, and regular Mojang.

Using Connect AuthSession API ​

The following examples are not active setup instructions yet. They show the type of configuration that may be needed once AuthSession support is released.

Velocity ​

shell
java -Dmojang.sessionserver=[MINEKUBE AUTHSESSION API COMING SOON] -jar velocity.jar

Gate ​

TBD. Standard Gate has first-class Connect support today. Gate Lite backend-route AuthSession/passthrough support is not available yet.

Waterfall ​

shell
java -Dwaterfall.auth.url="[MINEKUBE AUTHSESSION API COMING SOON]?username=%s&serverId=%s%s" -jar waterfall.jar

Paper ​

Note: These instructions only apply if you are running Paper standalone and NOT under a proxy. If you are using Gate, Velocity, Waterfall, or Lilypad, you should have already configured this, and you can safely skip this section.

Add the following CLI flags to your start script:

shell
-Dminecraft.api.auth.host=[MINEKUBE AUTHSESSION API COMING SOON]
-Dminecraft.api.account.host=[MINEKUBE AUTHSESSION API COMING SOON]
-Dminecraft.api.services.host=[MINEKUBE AUTHSESSION API COMING SOON]
-Dminecraft.api.session.host=[MINEKUBE AUTHSESSION API COMING SOON]

When you are done, your script may look something like the following:

shell
java -Dminecraft.api.auth.host=[MINEKUBE AUTHSESSION API COMING SOON] \
     -Dminecraft.api.account.host=[MINEKUBE AUTHSESSION API COMING SOON] \
     -Dminecraft.api.services.host=[MINEKUBE AUTHSESSION API COMING SOON] \
     -Dminecraft.api.session.host=[MINEKUBE AUTHSESSION API COMING SOON] \
     -jar paper.jar

In addition, ensure that you have set enforce-secure-profile to false in your server.properties file.

Lilypad ​

Set the following environment variable:

LILYPAD_MOJANG_SESSIONSERVER_URL to [MINEKUBE AUTHSESSION API COMING SOON]

BungeeCord ​

This proxy type is currently not supported due to an issue in BungeeCord; please use Gate, Velocity or Waterfall instead.

Compatibility ​

Only the listed software allows changing the Mojang AuthSession API url. Bungeecord is not supported.
