Download

The recommended installation file is the normal release JAR:

Download Account Manager v1.0.1

You can also browse all published versions on the Releases page.

Do not install a -sources.jar file as the normal mod.

Current Minecraft Services Status

Microsoft OAuth sign-in is implemented and works through the standard Microsoft authentication flow.

Minecraft manually reviews new third-party applications that request access to the Java Edition game service APIs. Until this application's Microsoft Entra Client ID is approved and added to Minecraft's allow list, Minecraft profile-service features may display App Not Authorized.

The mod does not use another launcher's Client ID and does not attempt to bypass Minecraft Services application authorization.

Installation

1. Install Minecraft: Java Edition 26.1.2.
2. Install a compatible Fabric Loader.
3. Install Fabric API for the same Minecraft version.
4. Download the normal Account Manager JAR from this repository's Releases page.
5. Place the JAR inside your Minecraft instance's mods folder.
6. Launch Minecraft with the Fabric profile.

Using Account Manager

Open:

Multiplayer -> Account Manager

From there you can sign in with Microsoft, inspect authentication status, open Profile Management, preview skins, validate Minecraft names, and refresh Minecraft profile information.

Support & FAQ

Why do I see App Not Authorized?

Account Manager's Microsoft authentication flow is implemented, but Minecraft Services access for new third-party applications is manually reviewed by Minecraft. Until this application is approved and allowlisted, Minecraft profile-service features may return App Not Authorized.

This can affect profile loading, IGN / UUID retrieval, skin uploading and Minecraft name changes. This notice will be updated once access is approved.

Which Minecraft version is supported?

Account Manager v1.0.1 is built for Minecraft: Java Edition 26.1.2.

Do I need Fabric API?

Yes. Install Fabric Loader and Fabric API for Minecraft 26.1.2 before launching the mod.

Which Java version do I need?

Use Java 25 or newer for this release.

Which file should I download?

Download the normal release file:

account-manager-1.0.1.jar

Do not install a -sources.jar as the normal mod.

Contact me directly on Discord: @te5rontop

How should I report a security issue?

Security

Account Manager is designed as a public/native desktop OAuth client.

• Microsoft authentication is performed in the user's system browser.
• No client secret is embedded in the mod.
• Access tokens are intended to remain only in memory while Minecraft is running.
• Tokens are not intentionally displayed in the UI or written to local configuration files.
• Clearing the account state invalidates the current in-memory authentication session.
• Stale asynchronous authentication results are discarded after a new sign-in or account clear.
• Minecraft Services requests use bounded connection/request timeouts.

Never send Microsoft passwords, access tokens, refresh tokens, Xbox/XSTS tokens, or authorization codes to anyone claiming to provide support for this mod.

Requirements:

• JDK 25
