To make the password prompts stop, you'll need to set up what's known
as SSH public key authentication. If you already have an SSH key pair,
you can append your public key to your authorized keys list as
follows:

cat .ssh/id_rsa.pub >> .ssh/authorized_keys

If you don't already have an SSH key pair, you'll need to run

ssh-keygen

and accept the defaults, and then run the command above to accept the
generated key.
