Indeed. Every device should get a passkey. Its like client certs where you can lose a device and just remove that passkey from your account. Also, you /can/ store passkeys in pure software. Bitwarden can store passkeys for example. Lots of options for FIDO keys too. I have never heard a non technical person give me a secure password strategy. That is 100% of nontechnical people I have asked use bad password schemes. Passkeys at least enforce a truly randomly generated key.

They still suck at usability but it is an attempt to solve a real problem. Basically the only thing standing between 99% of people and having all their accounts compromised is service password attempt rate limiting.
