Is there an api to get the bearer token set by KeyCloak?

This seems like something we should have easy access to now that we are using Web sockets that have their own authentication.
The current persona contains:

createdAt: "2015-09-10T14:51:06.173Z"
id: "28026b36-8fe4-4332-84c8-524e173a68bf”
name: "John Doe"
updatedAt: "2015-09-10T14:51:06.173Z”

Can we get authenticationToken added to this?

Or is there another better way?
