When using 'scp' instead of 'ssh' for tramp transfers, you are
prompted for your password when you connect, each time you visit a
file, and each time you write a buffer back to the remote host.

There is a 'password.el' file which can cache the password.  It's a
part of both tramp and gnus, but in newer versions than are in Emacs.

To see it in tramp, visit:

  /scp:localhost:/tmp/

(with an sshd running on your local machine, and without ssh-agent,
ControlMaster or any other means of skipping password entry).  Try
visiting a file and saving it back.

Try again with /ssh: instead of /scp: and see how it only prompts for
the password once.
