YubiKey Hardware Token and PrivacyID3A

Hi All,

Has someone implemented a 2FA/MFA with YubiKeys or other Hardware Tokens.
Preferable not some kind of Hardwaretoken Cloud vendor lock-in (like using the Yubi-Cloud) but
something selfhosted like PrivacyID3A.

I found only an old (2018) post about Yubikeys:

Kind Greetings,
