title: Multiple users same browser asp identity
body: <p>We have an application which has two user types. One of them is an administrator and the other one is a client. We are using AspNet identity to authenticate the user and issue a cookie. 
  However, there is a scenario where the administrator and the user share the same browser. When the client logs in, the cookie gets overridden and when coming back to the administrator pages we lose authentication. The same happens the other way around (client is logged in first, then admin). 
  Is there a way to support multiple authenticated users at the same time on the same browser?
  Greetings.
