ed25519-sk key type not working ?

[nono]

Hi Everyone,

I recently bought a security key (Yubikey/Nitrokey type) and create a new pair of ed25519-sk type.
I'm a bit surprised that I'm not able to use on a:

OPNsense 23.4.2-amd64
FreeBSD 13.1-RELEASE-p8
OpenSSL 1.1.1v 1 Aug 2023

When my "normal" ed25519 works perfectly.

Is there something I can do to allow such ssh key type ?

[nono]

My bad .... I paste the wrong public key to my user access  :-[
