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...
Probably, but the real problem has been database dumps for a good number of years now. Maybe this thing fixes that?
That is true. That has been, and (for some dumb reason) continues to be, a real problem.
