Nope.  The fact that they get a password prompt at all is confirmation
that <somewhere> exists, and if your login name on <somewhere> isn't the
same as your login name on the local host then it must be configured
locally in ~/.ssh/config.  The password authentication prompt isn't
issued until the client has already provided all that information to the
server.
