Assume that you need a passwordless access to TARGET computer via SSH from ORIGIN computer. You need an authorization key for that:

user@ORIGIN> ssh-keygen -t rsa
user@ORIGIN> cat .ssh/id_rsa.pub | ssh user@TARGET 'cat >> .ssh/authorized_keys'

Note: ssh-keygen will ask you to type then name for a generated key. The default name is id_rsa.pub.

Hint: This allows you to use automatic completion when using scp.
