title: How does one secure a tableau report when it is embedded in a web application?
body: <p>I'm new to Tableau and was wondering if someone could explain to me how report data is secured when the report is embedded in a website or web application (e.g. ASP.NET)?  From my research, it looks like there are two ways to embed a Tableau report:</p>
  
  <ul>
  <li>Using an iFrame</li>
  <li>Through the Tableau JavaScript API</li>
  </ul>
  
  <p>Neither of these methods seem very secure, however, without requiring the user to log in to the Tableau server, which would require a double-login (first login to the web application and then a second login to the Tableau server) and thus be undesirable.</p>
  
  <p>Can someone post a link, or otherwise help me to understand how security works with Tableau reports?  I am really impressed with Tableau, but don't understand this aspect yet.</p>
  
  <p>Thank you in advance.</p>
