Authenticator issues

[ThatBlockyPenguin]

Hello! I have recently found this project, but whenever I try to launch minecraft using it, I get this error:

[MCLC]: Parsed version from version manifest
[MCLC]: Set native path to C:\Users\PixelOrangeDev\Documents\Programming\NodeJS\MeteorMC\minecraft\natives\1.14

                throw new Error("Validation error: " + response.statusMessage);
                ^

My lauchMinecraft file contains this:

const { Client, Authenticator } = require('minecraft-launcher-core');

let opts = {
    clientPackage: null,
    authorization: Authenticator.getAuth("BlockyPenguin", "**My Password**"),
    root: "./minecraft",
    os: "windows",
    version: {
        number: "1.14",
        type: "release"
    },
    memory: {
        max: "6000",
        min: "4000"
    }
}

const launcher = new Client();
launcher.launch(opts);

launcher.on('debug', (e) => console.log(e));
launcher.on('data', (e) => console.log(e.toString('utf-8')));
launcher.on('error', (e) => console.log(e.toString('utf-8')));

Can anyone help me please? thank you!

This error is caused by using an incorrect email/username and password.

instead of using your username, use your email. Username is only for unmigrated accounts
