The difference between RCP and SCP:

rcp copies files or directories remotely through rsh, and the SCP copies files or directories remotely via SSH.

RCP is an insecure way to transfer files, and SCP is more secure, but it is possible for the SCP command to be executed with the user entering a password and passwords.
