To avoid entering password on every login to remote server you can add your public ssh key to ~/.ssh/authorized_keys on your server
To do so, first get your public key(usually it's ~/.ssh/id_rsa.pub):
cat ~/.ssh/id_rsa.pubNow copy it contents and on remote server run:
vi ~/.ssh/authorized_keysand save the file(:wq)
