Msamc NPM | npm.io

MS Account for Minecraft Login

💻 Login to Minecraft (Java) using a Microsoft account.
👌 Compatible with MLC (minecraft-launcher-core).

Installation

npm install msamc

Usage

Without MLC:

const msamc = require("msamc").default;

new msamc("YOUR_APP_ID").Authenticate().then((auth) => {
  console.log(auth);
});

The auth object will contain the following properties after a successful authentication:

{
  MinecraftProfile: {
    {
      id : "REAL_USER_UUID",
      name : "SOME_USERNAME",

      skins : [
        {
          id : "SOME_UUID",
          state : "ACTIVE",
          url : "http://textures.minecraft.net/texture/SOME_UUID",
          variant : "CLASSIC",
          alias : "STEVE"
        }
      ],

      capes : [ ... ]
    },
  },

  MinecraftToken: "MINECRAFT_ACCESS_TOKEN",
  XBLToken: "XBL_TOKEN",
  XSTSToken: "XSTS_TOKEN",

  mlc: {
    uuid: MinecraftProfile.id,
    name: MinecraftProfile.name,
    access_token: MinecraftData.access_token,
    user_properties: "{}",
    meta: {
      type: "msa",
      demo: false,
    },
  },
}

With MLC:

const msamc = require("msamc").default;

const mlc = require("minecraft-launcher-core");

new msamc("YOUR_APP_ID").Authenticate().then((auth) => {
  const client = new mlc.Client();

  client.launch({
    authorization: auth.mlc,
    root: "path/to/minecraft",
    version: {
      number: "1.16.5",
      type: "release",
    },
  });
});

In the terminal, it will give you a code and ask you to open a link in your browser. Once you have opened the link, you will be asked to enter a code. This code will be used to authenticate you.

In the future, I plan to add a legacy message box to display the link and the code, instead of displaying them in the terminal.
