They are using GPG Authentication subkeys for SSH.
I have them on a smartcard and it works really well (you can also connect Yubikey 4C to Android via OpenKeychain and login to servers using Termbot on the go using hardware stored keys - secure and convenient!).
- infogulch 8y agoAh so I'm just much more cavalier with my ssh keys. The 4C looks interesting though, thanks for the recommendation!
- Boulth 8y agoNowadays it's probably 5C, or 5 if you need USB-A connector. An added benefit of Yubikey backed keys is touch to use so that you need to physically touch the token to use the key. A critical matter when using ForwardAgent! [0]: https://developers.yubico.com/PGP/Card_edit.html https://developers.yubico.com/PGP/Card_edit.html
