Authenticate
A Minecraft Fabric mod that provides player authentication functionality for servers.
Quick answer
Which Authenticate release should I use?
Authenticate 26.2-1.1.1 targets 26.2 with Fabric. Do not install it on the client. It must be installed on the dedicated server. 1 required mod needs a matching file.
Where it goes
Is Authenticate required on the client, server, or both?
Do not install it on the client. It must be installed on the dedicated server.
This file is marked server-only.
What else does Authenticate 26.2-1.1.1 need?
26.2-1.1.1. Change the file and its required mods may change too.
Install Fabric API, Fabric ORM Jimmer, Fabric Database H2, Fabric Language Kotlin first, but 1 required mod has no matching file for this setup. Do not mix loader builds to force a match.
We only count dependency files that match this setup. A file for another loader does not fill the gap.
