2FA Authentication

A simple npm package for 2FA (Two-Factor Authentication) using TOTP (Time-Based One-Time Password) and QR codes.

Installation

Install the package using npm:

npm install 2fa-auth

Usage

1. Generating the QR Code

Use the generate.js script to generate a QR code and save the secret.

generate.js

const fs = require('fs');
const TwoFactorAuth = require('2fa-auth');

const twoFA = new TwoFactorAuth();
const user = '[email protected]';

twoFA.generateQRCode(user, (err, qrCodeImage) => {
  if (err) {
    console.error('Failed to generate QR code:', err);
  } else {
    console.log('QR Code Image:', qrCodeImage);

    // Save the secret to a file
    const secret = twoFA.secret;
    
    console.log('Secret Key ', secret);
  }
});

2. Verifying the Token

Use the verify.js script to verify the token generated by a 2FA app using the secret key.

verify.js

const TwoFactorAuth = require('2fa-auth');

const secret = 'BQKBELJ3B4BHYJQF';
const twoFA = new TwoFactorAuth(secret);


const token = '777427';

const isValid = twoFA.verifyToken(token);
console.log('Is Token Valid?', isValid);
