Keychain: In-Game Account Manager
by Domsimus
Keychain: In-Game Account Manager lets a player switch between Microsoft and offline Minecraft accounts without leaving the game or reopening the launcher.
What it does
Keychain adds an account manager to the game itself. Accounts can be added through Microsoft sign-in in a browser, or created as offline profiles, and the saved list is reached from the main menu or the pause menu. Choosing an entry from the list switches the active account without a restart, so a launcher round trip is no longer needed for each change.
The mod is aimed at players who keep several Minecraft accounts and want a faster way to move between them. Authentication goes through Microsoft's official service, and the mod uses OAuth 2.0 with PKCE, so the Microsoft password is entered on Microsoft's page and never typed into the mod. Tokens refresh automatically when an account is switched. Offline accounts grant Minecraft ownership in the sense that they bypass server authentication.
Installation requires Fabric Loader and Fabric API for a supported Minecraft version. The mod is client-side only, so servers do not need it, and it is open source under the MIT License. Builds cover 1.21.11 – 26.3 across six release versions, with 3.0 for 26.3 as the latest Fabric file.
Key features
Microsoft account switching
Accounts signed in with real Microsoft logins can be switched in-game, with the saved list shown as one interface.
Offline profiles
Offline accounts can be created and kept in the same list as Microsoft accounts, then selected like any other.
Player skin previews
The account list shows a skin preview for each saved profile, so the right one is identifiable before switching.
Main and pause menu access
The manager opens from both the main menu and the pause menu, so switching does not depend on the title screen alone.

How it compares
AccountSwitcher is Fabric-only, for 1.21.4, and released under All rights reserved, so its source is not open. AutoLogin is open source under the MIT License and is published for Fabric 1.21 – 26.3, with the same client-side only environment as Keychain. OAuth Account Manager is open source under the Apache License 2.0 and covers Fabric, Forge and NeoForge, but only for 1.21.1; it is also client-side only.
