Solo 2 not recognized as a passkey

I just noticed that the forum allows me to set up a passkey in my profile. Although I don’t really need any great security just for chatting here, I tried to set it up anyway. My Yubikey works fine, but my Solo 2 from is not recognized. Does your web site allow only certain devices for passkeys? If so, and if you want to make it perfect, please consider adding Solo 2 to the list of allowed passkeys. Thanks!
