SSH key access to VPS Sensitive Access
The skill creates and uses SSH keys (~/.ssh/frp-vps) for VPS access. The key is generated without passphrase for automation convenience.
ssh-keygen -t ed25519 -f ~/.ssh/frp-vps -N ""
→ Document that passphrase-less keys are for automation only and should be protected at rest.
