title: Adding extra details to a webapi bearer token
body: <p>I am trying to learn the new webapi2.1 authentication pieces.</p>
  
  <p>I have got the bearer token wired up and working with my webapi. My next thing I would like to do is be able to store some additional information within the token (if possible) so when the client sends back the token I can retrieve the details without the need of them sending multiple values.</p>
  
  <p>Can the token be extended to contain custom data?</p>
  
  <p>Sorry if the question is a little vague but I have had a big hunt around and can't seem to find any further information  </p>
  
  <p>Thank you</p>
