Bitwarden has clients for Windows and Linux, and extensions for Firefox, Chrome. You can use passkeys this way. I self-host Bitwarden (vaultwarden) and this is how I use passkeys, via Android app and Firefox extension on Linux. IDK if the flatpakinux client would allow you to use passkeys.
Is there any way to use passkeys without anything Google or Apple or smartphone?

Hm, I do host myself a vaultwarden-web instance and I don’t see an option for passkeys. Time to update I guess, although it’s not that old - 2024.1.2
