We had originally planned to go all-in on passkeys for ONCE/Campfire, and we built the early authentication system entirely around that. It was not a simple setup! Handling passkeys properly is surprisingly complicated on the backend, but we got it done. Unfortunately, the user experience kinda sucked, so we ended up ripping it all out...
If you think that I’m misunderstanding something and arguing from a false premise then please feel free to engage with the discussion.
I don’t think that, you said that. It’s the very first sentence of your comment. You literally said that you misunderstood them to be hardware keys.
And yes, everything else you said is demonstrably false as well. The FIDO alliance and even specifically the companies within it that are pushing Passkeys the most, are advocating for them to be cross platform without any lock in. 1Password is one of the companies pushing for passkeys, they’re even behind the https://passkeys.directory and allow you to securely import and export passkeys so you aren’t locked in. They also made recent changes to the spec itself to make moving and owning passkeys easier. And that’s not even to mention the fact that Passkeys are just key pair, which don’t require any platform or technology to implement that isn’t built into your device.
