title: How do I add Enhanced Security Login to my website
body: <p>I am developing an ASP.NET website and wanted to add another layer of protection to my users.</p>
  
  <p>When they login from a new machine then they would need to setup that new machine with my website after answering 3 security questions.</p>
  
  <p>How can I do this?</p>
  
  <p>Cookies? Is there any other way?</p>
  
  <p>Thanks!</p>
