I have a desktop and laptop that I use for development. I generated an ssh key on the primary machine (desktop) to my vps which uses a passphrase. In terms of best practices or security concerns, is it better to generate a new ssh key on my laptop to the same vps, or should I just copy the ssh keys from the desktop to the laptop.
Everything i've read on the topic simply explains how to copy ssh keys from one computer to another. I haven't seen anything explaining the pros/cons of generating a new key vs copying an existing one. (both machines are used solely by me).
