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...
The problem with PassKey is simply that they made it way more complicated.
Anyone who has worked with SSH keys knows how this should work, but instead companies like Google wanted to ensure they had control of the process so they proceeded to make it 50x more complicated and require a network connection. I mean, ok, but I’m not going to do that lmao.
Private keys on an anonymous, untraceable smartcard. PIN or Matching-on-card fingerprint for the second factor Everything else can go directly into the garbage bin
