Lyumix Discord Auth
Lyumix Discord Auth lets server owners require players to verify their identity through Discord before they can join, with optional auto-login for trusted players.
What it does
Players authenticate through Discord on a server running the mod, and the server keeps their login state between sessions. Auto-login can be configured for trusted players, and login timeouts and IP-based auto-login are also adjustable. On first start the mod generates its configuration files, so server owners can check the options before opening the server.
Authentication data is stored in SQLite by default. MongoDB and PostgreSQL are supported as alternatives for servers that already run a database. The mod is built to add little load to the server, and the authentication flow is kept short for players. Fabric API is required, and the mod is published for Fabric only, in two game versions: 1.21 and 1.21.1, with 2.1.0 for 1.21.1 as the latest file. It is open source under the MIT License.

Use cases
Private survival servers
Owners of small servers can limit access to players who verify through Discord before joining.
Servers with a Discord community
Communities that already coordinate on Discord can use the same accounts to control entry to the game server.
Who it’s for: Server owners who want Discord verification and a choice of database, and who run Fabric servers on 1.21 or 1.21.1. Players need nothing installed on their side.
How it compares
MineAuth is also a Fabric server-side mod under the MIT License, but its files target 1.21.11 and it is open source. Serverauth Mod is server-side only under the MIT License for 1.20 – 26.1.2, and it is not open source. EZLogin is client-side only, under the Creative Commons Attribution Non Commercial 4.0 license, and is not open source, so it does not run on the server side like this mod.
