You have to copy your private key onto the remote machine, and add it
to .ssh/authorized_keys. For example:

on local machine do:
ssh-keygen -t rsa
scp ~/.ssh/id_rsa.pub user@remote:~/.ssh/my_key
login to the remote machine, and:
cd ~/.ssh
cat my_key >> authorized_keys
rm my_key

You're done.

PS. Some paths may vary depending on local and remote machine' OS.
