Dual Account

by smilejian

Dual Account lets one Minecraft account join a Forge server through several clients at the same time, with each connection given its own session.

ForgeServer-side onlyMIT License1.20.1 – 1.20.6

What it does

Normally a Minecraft server accepts only a single connection for each account. Here, every client that signs in with the same account gets a separate session carrying its own unique UUID, so the server tracks each one on its own and players can interact with each other normally. Each session behaves like a completely separate player, although it still uses the same Minecraft account.

The original account information is used only for authentication when a player joins. Server owners who want several characters under one login, such as Steve, Steve 1, Steve 2 and Steve 3, can run them side by side. Installation is on the server only; clients join without any change. The code is under the MIT License and is not open source in the sense of a public repository listing, so its terms are the MIT License text.

Files exist for Forge only, for six game versions, with 1.0.0-alpha for 1.20.6 as the latest file, published on 2026-07-19 on the alpha channel. Official builds are maintained by SMILEJIAN, the mod's author.

Key features

  1. Multiple sessions per account

    Several clients can connect with the same account at once, each receiving an independent session.

  2. Unique UUID per connection

    Every connection gets its own UUID, which the server uses to track that session separately.

  3. Separate player data

    Each session keeps its own player data, so inventories and progress do not merge across connections.

  4. Player interaction

    Sessions created from one account can see each other, deal damage and interact like ordinary players.

  5. Authentication only

    The original account is used only to authenticate the login, not to link the sessions afterward.

Use cases

Multiple characters on one login

A player who owns one account can run several characters on a server without buying more copies of the game.

Server testing

Server owners can log several test clients in at once to check how players interact on the same server.

Who it’s for: Server owners running Forge who want more than one connection per account. Clients need nothing installed, since the mod runs on the server side only.

Questions

Does Dual Account have to be installed on the client?

No. It runs on the server alone, so players need nothing extra to join.

Which Minecraft versions does Dual Account support?

Files exist for Forge across six game versions, 1.20.1 – 1.20.6. The latest file, 1.0.0-alpha, targets 1.20.6.

Are the sessions linked to each other?

No. Each connection receives an independent session with its own UUID, and the original account is used only for authentication.

What the author says

Dual Account is a server-side Minecraft Forge mod that allows multiple Minecraft clients to join the same server using the same Minecraft account at the same time. Normally, Minecraft servers only allow one connection per account. This mod removes that limitation by creating a unique session for every connection.
