Check http://masashi-k.blogspot.com.br/2013/06/sending-mail-with-gmail-using-xoauth2.html to register your application.

You will need something like this to authenticate on Gmail:

var xoauth2 = require('xoauth2');
var nodemailer = require('nodemailer');
var smtp = require('nodemailer-smtp-transport');

var generator = xoauth2.createXOAuth2Generator({
  user: '..',
  clientId: '...',
  clientSecret: '...',
  refreshToken: '...',
  accessToken: ''
});
generator.on('token', function(token){
  console.info('new token', token.accessToken);
  // maybe you want to store this token
});

var transporter_google = nodemailer.createTransport(smtp({
  name: '...',
  host: '...',
  port: 587,
  secure: false,
  ignoreTLS: false,
  tls: { rejectUnauthorized: true },
  debug: false,
  auth: { xoauth2: generator }
}));
