TwinSession
by MisterFish
TwinSession lets one Minecraft account join the same server world several times at once, so a player can run separate tasks in parallel.
What it does
Normally a Minecraft account can hold only one connection to a server at a time. TwinSession removes that limit for Fabric: a second connection from the same account is accepted, and each extra session has its own client window. This suits players who want to run several in-game jobs at once, such as managing farms or automation, without buying additional accounts. It is aimed at players who want to multitask in a single world.
When the same account connects a second time, the mod changes the player's username on the server by placing a number before the name and an underscore between them, for example 1_PlayerName. Each additional session raises the number, giving 2_PlayerName, 3_PlayerName and so on, so the sessions can be told apart in the player list. The server must run the mod, and players may add it on their side as well.
Files are published for Fabric only, for game versions 1.20 – 26.1.2 with 22 release versions. The latest Fabric file targets 26.1.2 and was released on 2026-05-17. The mod is open source under the CC0 1.0 Universal license, and its source code, issue tracker and wiki are public.
Key features
Multiple connections per account
One Minecraft account can connect to the same server world more than once, each connection in its own client.
Automatic username numbering
Each extra session adds a numbered prefix to the username, such as 2_PlayerName, so sessions are simple to tell apart.
Parallel in-game tasks
Separate sessions let a player manage different jobs, such as farms or automation, at the same time in one world.

How it compares
RpSessionMod is a Fabric client-side only mod with All rights reserved licensing and files for 1.20.5 – 26.2, so it adds nothing on the server. Simpler Auth is a Fabric server-side only mod under the MIT License for 1.16.5 – 1.19, and it handles logins rather than multiple sessions. TwinSession differs from both by requiring the server, by being open source under CC0 1.0 and by covering 1.20 – 26.1.2.
