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...
I can use bitwarden on Windows, Linux, Mac, iOS, Android, on desktop app or using CLI. That’s a stark difference in comparison with built in Microsoft or Apple keychains. And yes, I trust Bitwarden.
