in case you may have not known, if you have a #yubikey or an #onlykey or something similar you can generate SSH keys that require them, for example:

`ssh-keygen -t ed25519-sk`

What is the -sk ending for ssh key types?

ssh-keygen has the following options for a key type (-t): dsa | ecdsa | ecdsa-sk | ed25519 | ed25519-sk | rsa I am not familiar with the -sk notation and it's not explained in the man page. What do...
