Hey Lars,

(a) sounds like a bug in Horizon if that's not viewable immediately after
creating the instance.  If we can confirm that is the case and file a bug,
that'd be good.  It just comes back via the API so it should be available
to any client.

(b) is definitely not going to work - we don't store the password at all,
an intentional decision.
