Thanks, I'll look into that product. Less costly, but still far from the $2 scenario. If hardware keys got to a super low price point, or even handed out for free or bundled with new phones or PCs, I image lots of people would prefer them over passkeys.
I am a yubikey user, but they are a terrible option for a normal person. Losing a hardware key means being locked out from all your accounts for real, and if cryptography taught me one thing it's that people are not responsible enough to manage their own keys (keep a backup key up to date, print recovery codes, etc)
