MultiYggdrasil

by QiuShui1012

MultiYggdrasil lets a Minecraft server accept logins from several Yggdrasil authentication services at once, including the official one and external servers.

FabricForgeNeoForgeServer-side onlyGNU Affero General Public License v3.0 or laterOpen source1.14 – 26.2

What it does

The mod is configured to point the server at one or more Yggdrasil API sources. Those can be the official Mojang service or other external authentication servers, so players who hold accounts on different services can join the same server. Only the server side runs the mod, and players join without installing anything.

Its configuration design draws on MultiLogin, and parts of its code come from authlib-injector, which is licensed under AGPL-3.0. The mod is released under the GNU Affero General Public License v3.0 or later and is open source. Files are published for Fabric, Forge and NeoForge for the 1.14 – 26.2 range.

Key features

  1. Multiple Yggdrasil sources

    A server can be set to accept accounts from several Yggdrasil API sources instead of only one.

  2. Official and external services

    The source list can include the official authentication service as well as other external servers.

  3. Server-side setup

    Configuration is done on the server, which requires the host-like values and MC version specifics listed in the mod's table.
