Use a QR code module to generate a QR code that stores the data in `secret.otpauth_url`, and then display the QR code to the user. This is one simple way to do it, which generates a PNG data URL which you can put into an `<img>` tag on a webpage:

// npm install --save node-qrcode
// Use the qrcode package
// npm install --save qrcode
var QRCode = require('qrcode');

// Get the data URL of the authenticator URL
