title: Saving login information on the heroku server in the whatsapp.web.js directory
body: <p>I recently uploaded my project 'whatsapp.web.js' to heroku.
  And I'm having a problem
  1 Because the server is being reset for some time.
  2 Because it is not possible to save files on the server then can not connect again
  I use the multi-device feature in whatsapp
  The question is is it possible to save the login information? And every time the server is reset it will reconnect</p>
