ssh-copy-id remote-machine

This one-liner copies your public-key, that you generated with ssh-keygen (either SSHv1 file identity.pub or SSHv2 file id_rsa.pub) to the remote-machine and places it in ~/.ssh/authorized_keys file. This ensures that the next time you try to log into that machine, public-key authentication (commonly referred to as “passwordless authentication.”) will be used instead of the regular password authentication.
