First of all I would recommend to change the port of ssh:
vi /etc/ssh/sshd_config
service sshd reload
Find line Port 22 and change it to some other number greater than 1024.
Then, you would like to login to the server without using password. This procedure is described here. By the way, if by that time you have changed your ssh port, don’t forget to add -p1024 (or other port used) tu ssh commands you use in this tutorial. What is more, it is recommended to set .ssh folder permissions to 700 and .ssh/authorized_keys to 640:
chmod 700 .ssh
chmod 640 .ssh/authorized_keys
