alt Hacker NewsI like the idea of using my MacBook's Secure Enclave for ssh keys but what do I do if I develop on a remote VPS (purely because I'd rather have the AI accidentally rm -rf / on a VPS than my own computer)?

You can use agent forwarding (ssh -A) to make your local hardware-backed key available on the VPS.
If you're using tmux on the VPS this can get a little tricky, because by default your tmux panes will inherit your initial SSH client's SSH_AUTH_SOCK; when you re-attach tmux in a different SSH session you'll no longer be able to authenticate with the local YubiKey. But I wrote a shell script that hooks into tmux to keep SSH_AUTH_SOCK working correctly with this kind of setup: https://github.com/mshroyer/socklink
