Passkeys work well with password manager. The password manager also stores the long random password to get in without passkey. The advantage is that passkeys are immune to phishing. Sites also turn off 2FA for passkeys which reduces the hassle.

Unless the spec authors declare your password manager to be on the official naughty list[1] and relying-parties choose to block clients on that list.

I think it's more than fair to document that some implementations lie about their intentional violation of the spec, even if that violation is done to make the login process smoother.

Still, I've never seen a website try to block Bitwarden's passkey management (though I've had plenty of issues because of its partial implementation of the API, especially in early versions) despite its spec violations.

For some of the implementations, user verification is a massive pain (as browser extensions often only have long and complicated passwords to authenticate) but for KeepassXC a quick and simple fingerprint/facial scan is an option, as it already offers integration into the native OS biometrics anyway.

Ideally it shouldn't be possible, or at least it should clearly be an ugly hack for a website to be doing something like this. Instead the spec authors explicitly endorse blocking clients that they feel are non-compliant. I'm not going to use a login spec that encourages websites to ban me because of the software I choose to use.

Man don't get me started on the passkey environment's bizarre obsession with biometrics. My desktop computer doesn't have a fingerprint reader or a camera, and if my OS (Arch Linux) supports that junk I've certainly got no interest in doing the work to set it up just so I can log in to a website.

Documenting is fine, but the passkey spec author has been recommending blacklisting these so they don't work. It will end in a situation where only the Apple, Google and Microsoft passkey managers are the only way to log into any website.

As I said earlier, this is functionally impossible because Apple devices don't offer device attestation data.

Then I look forward to them removing the anti-feature and no longer maintaining the naughty client list.
