You say 2FA several times, but you say to skip the passphrase. You really then have two of the same factor, something you have (private key and yubikey). Better than just one, but not 2FA. you need a passphrase on it (something you know) for 2FA.
Again, great how to, I will be using this as a guide, with the addition of a passphrase.

Windows users should bear in mind that they either need to use the Linux subsystem or install Powershell OpenSSH beta which is not easy to find. The integrated SSH as of now is too old.

If you do not add a comment using the -C option it will put something like “username@yourlocalmachine” as the key identifier. This is confusing since you may register more than one key on the same machine but use them on different machines. So better to use something like -C ‘Yubikey A’.
Not all servers do yet support this rather new feature so I had to give up and use normal SSH keys instead.

Incredible, I’ve searched many sites but they all have complicated instructions and in the end the solution didn’t even work. I followed your “simple” instructions and like magic it worked! Unfortunately, however, I have a problem that blocks me. The key creation operation with the private key memorization in the yubukey, I did in a computer with linux on board. In the .ssh folder I found the file with the .pub extension and another file with the same name but without extension, opening this last file I find private key written at the beginning, is it the private key or is it just a link? But that’s not so much the problem, the problem is that the connection to the remote server doesn’t work for me if I try to connect from a MAC. The version of openssl on the MAC is “OpenSSH_9.0p1, LibreSSL 3.3.6”. The MAC .ssh folder contains only the known_hosts file. Do you have any advice for me?
