I think passkeys will be used against users. They’ll be used to attest to a user’s trustworthiness by tying authentication back to a real identity. Like another comment mentioned, you’ll end up needing something like a phone that’s locked down. Part of that will be authenticating with a verified ID IMO.

It’ll be incredibly easy to lock dissenters out of modern society. It’s too bad the vast majority of users will happily concede autonomy for a tiny bit of short term convenience.
