This sort of shit is the reason they will never get me to use their passkey implementation.

The sooner there's a truly portable open source offline version of passkeys I'm all in. Until then I'm sticking with my password manager.

I do feel the only thing you can really trust from Google are the things that make them money. Chrome, and any software that allows them to hook into for advertising money. It makes me worry about go, dart, and flutter. Though the latter two include analytics which you need to disable.



There is a pull request for adding passkeys to KeePassXC:

Interesting to see that passkeys make use of CBOR. When I looked at binary JSONs several years ago, Smile was one of my favorites, but CBOR was decent too.


Amazing thanks for this, I was unaware. Hopefully not too long.


I believe security keys are the offline version of passkeys you're looking for.

I am afraid that websites will somehow disable support security keys and only support passkey implementations from big tech (similar to how websites only offer signin with google, fb , etc).

Can someone clarify if WebAuthn protocol allows for this filtering against hardware authenticators?


yes, there's an attestation cert as part of the register request


I hear that the way Big Tech implements passkeys means that it is impossible to require attestation to prove use of their implementations.


I wouldn’t be surprised if you’re right, but I think it’s not all bad to only use auth from big tech - I don’t know if I trust most small companies to implement uname/password auth correctly. Most users recycle passwords too so a leak is really bad.

I think the reason to only support big tech passkey auth is because users (at scale) can’t be trusted to keep track of their hardware keys.
