Type "chmod 700 ~/.ssh" and press "Enter." Type "ssh-keygen -t rsa" and press "Enter." The initial key will now be generated. Press "Enter" when chosen for a filename.

Increase the security level, if you wish, by typing "ssh-keygen -t sa -b 4096" and pressing "Enter."

Transfer your key to the remote host to complete the setup process. Type "ssh-copy-id USER@HOST" -- replacing "USER" and "HOST" with the relevant username and host address. Press "Enter."

Log in to that host using "ssh USER@HOST" to utilize your SSH keys.
