scp uses ssh.
You can avoid multiple invocation (and authentication) by means of tar over ssh.
With rsync (extra package, usually in /opt/csw/bin/) you can do the same, and further avoid unnecessary copying (if destination file is already present and identical).
Finally you can generate ssh keys that can do authentication.
Details have been posted in several other articles already.
