XBridge

Encrypted Authentication for Offline Accounts and proxy setups using Microsoft Xbox Auth and Bedrock edition style auth.

XBridge is a Fabric client and server mod that replaces the need to type passwords in chat (like /login password) on insecure offline mode servers. Instead, it lets you log in through the official Microsoft Xbox portal, giving you instant access to your Bedrock character, gamertag and player data (if played with geyser before). It is as secure as official Mojang login, preventing any spoofing, and other hacking. completely encrypted process. Project is open source and I welcome any contributions :)

IMPORTANT: if the clients do not have the mod, the server side mod is bypassed completely and your backup login or premium players will take over for those specific players.

For normal people:

• Both Servers and Client mods are combined into one file, just download one file, it will work on both server and client/game.
• On server side, it needs no setup, just put on the fabric mod and it will work. No need to disable Online mode, premium players can join normally completely fine.
• For Players, put on the fabric mod, and when you are on multiplayer screen, click a new button in the corner "xbox login", it will open microsoft login page, just enter your email, password of xbox profile/MS account (completely free, and if you have a bedrock account, it is already made in that case, just sign in), then come back to game and you will see a toast saying successfull. This is permanent login as long as you don't reset the game. no passwords everytime, no commands, nothing.
• Then whenever you join a server with XBridge support, it will work flawlessly, it will automatically verify, authenticate with microsoft and you will join the server with your bedrock username (and also the skin if you ever played on ageyser server before)
• If skin doesn't load, you can just use the command /xskin url to use any skin png. ONLY ONCE on first join, it is them permanent on the server.
• One more amazing feature is the integration with geyserMC, if you use same microsoft account as you use to play from bedrock using geyser, it will be same player in the world, no double identities, only one you if you are logged in to same account.

Features

• Perfect for "Offline" Players and Proxy setups: Gives players without a Premium Java account a secure encrypted way to join servers using a free Xbox profile, NO SPOOFING OR HACKING possible. (theoretically)
• Keep Online Mode ON: Server owners do not need to turn off online-mode or compromise server security. Premium Java players continue to join normally, while XBridge players join using Xbox authentication automatically.
• Real Xbox Login: Log in through the official Microsoft website. Your password is never seen by the server.
• Play as Your Bedrock Character: Join the server using your exact Xbox Gamertag and Bedrock skin or use a custom skin. This makes it physically impossible to spoof the username at all.
• Log In Once: The mod securely remembers your login. You do not need to log in every time you launch the game.
• Proxy Support: Main use case for the Project
• Automatic Bedrock Skins: If you have played on a Geyser Crossplay server before, your Bedrock skin will automatically load for everyone to see.

Installation

You only need to install this if the server you are joining requires it or supports it.

1. Download the xbridge-fabric-universal.jar file from modrinth/curseforge.
2. Place the jar file into your Minecraft server and client mods folders.
3. Make sure you have the Fabric API installed for your version of Minecraft.
4. Launch the game and login with the button, then join the server directly.

Frequently Asked Questions

My skin is showing as a default character?

If your Xbox account has never joined a geyser cross-play server before, the global database might not have your Bedrock skin saved.

You can easily fix this by uploading any custom skin manually:

1. Find a skin you like online and get the direct image link (it should end in .png).
2. Type /xskin https://link-to-your-skin.png in the game chat.

Your new skin will be applied immediately and everyone on the server will be able to see it.

Do I need to own Minecraft Bedrock Edition?

No. You only need a free Xbox Live account (a Gamertag) to log in.
