yubikey-agent is a seamless ssh-agent that stores SSH keys on YubiKey hardware via the PIV smartcard interface. It runs in the background, survives unplug/sleep, and requires a PIN and physical touch for each login.
Use cases
- use a YubiKey as an SSH key for server logins
- set up hardware-backed SSH authentication easily
- require touch and PIN for every SSH login
- keep SSH private keys non-extractable on a smartcard
- replace ssh-agent with a YubiKey-backed agent
- configure per-host SSH agent selection
When to choose
- you want hardware-protected SSH keys on a YubiKey with minimal setup
- you need an agent that tolerates sleep, suspend, and unplugging without restarts
- you want maximum compatibility with standard SSH servers
When to avoid
- you don't own a YubiKey or PIV-capable smartcard
- you need Windows support, which is still work-in-progress
- you want fully automated logins without PIN entry or physical touch
