electron-device-id

Get a unique machine/device ID on macOS, Windows, Linux, and FreeBSD. No native dependencies — uses built-in OS commands.

Install

npm install electron-device-id

Usage

const { machineId, machineIdSync } = require('electron-device-id');

// Async (recommended)
machineId().then(id => console.log(id));

// Sync
const id = machineIdSync();
console.log(id);

By default the ID is hashed with SHA-256. Pass true to get the raw original value:

const raw = machineIdSync(true);   // original hardware UUID
const hashed = machineIdSync();    // sha256 hash (default)
