In case you often connect to remote server and get bored of typing the password all the time, there is a solution.
Create a public key, running the command
$ ssh-keygen -t rsa
A file ~/.ssh/id_rsa.pub will be created with your public key.
Now, publish the key to the server
cat ~/.ssh/id_rsa.pub | ssh USER@DOMAIN.COM "cat >> .ssh/authorized_keys"
And this will be the last time you will be asked for the password. Test if everything went as expect executing
ssh USER@DOMAIN.COM
You should login immediately, without being asked for the password.
