Thanks to a great suggestion by Nick Charlton, I decided to put together a screencast demonstrating how to set up public key authentication for logging into SSH servers on the Mac.
Setting up a keypair and then using it to log in to remote systems, instead of remembering separate usernames and passwords, can be a bit of a fiddly business, but I hope that in this screencast I can show how to get it set up.
