title: Authenticate a Cognito user without Federation in Unity
body: <p>I've been digging through AWS documentation but have not been able to find an example of using an unfederated login method for cognito in a Unity application.</p>
  
  <p>For example:</p>
  
  <p><a href="https://docs.aws.amazon.com/mobile/sdkforunity/developerguide/aws-unity-dg.pdf" rel="nofollow noreferrer">https://docs.aws.amazon.com/mobile/sdkforunity/developerguide/aws-unity-dg.pdf</a>
  <a href="https://docs.aws.amazon.com/sdkfornet/v3/apidocs/Index.html" rel="nofollow noreferrer">https://docs.aws.amazon.com/sdkfornet/v3/apidocs/Index.html</a>
  <a href="https://docs.aws.amazon.com/mobile/sdkforunity/developerguide/getting-started-unity.html" rel="nofollow noreferrer">https://docs.aws.amazon.com/mobile/sdkforunity/developerguide/getting-started-unity.html</a></p>
  
  <p>In all of this documentation I can't find a single reference for authenticating a user <em>without</em> using a federated identity method, such as facebook.  Is there just no support for this in their SDK?  Am I stuck using the HTTP API?  </p>
  
  <p>If anyone has any samples or experience I would much appreciate the advice.</p>
