They are not referring to passkeys. They’re referring to deterministic algorithms for uniquely labeling a particular device or person, despite any privacy enhancing features that device or person employed. It can be as simple as sampling various hardware specs, hashing the result, and using that as an ID for the person. So, if you switch browsers, they know it’s still you. More complex techniques exist, obviously.

I know how device fingerprinting works, thank you though. >You don't need my fingerprint, hardware or personal, or biometric shit. To me that sounds like hardware identifiers, but also quite specifically the things passkeys use. Hence I mentioned it as aside from their main point, which was "don't track me", because the biometrics GitHub or any website is going to ask you to use *can't* be used for that.
