// message from the host, then calls the |TokenFetcher| asynchronously to
// request a |token| and |shared_secret| from that url. If the server requires
// interactive authentication, the |TokenFetcher| implementation will show the

// to the host, and uses the |shared_secret| to create an underlying
// |V2Authenticator|, which is used to establish the encrypted connection.
