In a PQ world if they have the stolen hash, they have the password. How is that different than the passkey world?
Little harsh to say I have NO idea what I am talking about, though.
I still don't agree that companies won't revoke their passkeys if we are in a PQ world.
If they don't, you are still in a better place than passwords. Each public/private key pair is unique for every domain, so a compromise in one place is not a compromise in others. Many people re-use passwords (even if you don't).
