First, create an SSH user and login to your VPS by following these instructions.
Once you've logged into the VPS type this command:
Follow the prompts.
Your SSH keys will live in your ~username/.ssh/id_rsa directory
If you'd like to set up passwordless authentication you'll next want to
- Create an authorized_keys file in your ~username/.ssh/id_rsa directory.
- Paste your public ssh key (from your computer) into the ~username/.ssh/authorized_keys file that you just created
- Lock down the permissions so that only your account can read the contents of your authorized_key file by running: chmod 700 ~username/.ssh/authorized_keys
You should now be able to SSH into your server without a password from your own computer by running this command: ssh firstname.lastname@example.org
