Add SOTP to your code

var express = require('express');
var app = express();
 
var sotp = require('sotp')(app, {
  secret: 'my-random-secret', // Required
  appName: 'My App Name', // Name to display in Google Auth App - Default = My App
  successRedirect: '/homepage', // URL redirection after authentication - Default = /sotp/test
  devMode: true // Shown secret QRCode on /sotp/secret - Optionnal - Default = false
});
 
app.get('/homepage', (req, res) => {
  res.send('This is the Homepage ! You are logged in.');
});
