Passwordless SSH/SFTP for dummies

To get SSH or SFTP access to a server without using a password you need to have a SSH key pair for each computer you want to be able to access the server from. In this document I’ll describe the steps you need to take to generate a key pair if you don’t have one already. If you do, you can use your public key(s) to get access to the server.
