SSH Without Password

The basis of this is that your ID must be in the list of authorized hosts in the server. So, for password-less login to work, generate your public key, and append it to the authorized_hosts file in the server.

To create a public key, from terminal do

ssh-keygen -t rsa

To copy to authorized_hosts file do

cat ~/.ssh/id_rsa.pub | ssh serveruser@server 'cat >> ~/.ssh/authorized_keys'

Test by 

ssh serveruser@server

If no password is asked, everything worked fine.
You can also do the following command to copy the key

ssh-copy-id serveruser@server
