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...
Really? I just used a passkey for the very first time with Google and Bitwarden and it worked quite nicely. What about passkeys is worse for you?
Just answered in a reply to a different comment.
