DCLink

DCLink is a Minecraft plugin that enables you to link your Minecraft and Discord accounts on a server. By default, only linked accounts can join, meaning players need a Discord account to play on the server.

Players only need to authenticate when they first join; after that, they are added to a local SQLite database.

As defined in the configuration file, a Discord account can be linked to one or more Minecraft accounts.

There are lookup commands both in-game and on Discord to see which players are linked to which Discord accounts, and vice versa.

Compatibility

DCLink is compatible with Geyser & Floodgate, so Bedrock players can use the same auth system as Java players.
