I assert you don't need to pass any arguments.

If there is a usable authentication key found, it is used to do an authentication try.

If not, ssh falls back to password auth — if the server allows it. If the server only accepts key authentication, you should never reach the point of fallback anyways, because key authentication succeeded.
