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 thought passkeys were supposed to be a hardware device?
This is typical embrace/extend/extinguish behavior from the large platforms that don’t want their web-SSO hegemony challenged because it would mean less data collection and less vendor lock-in.
The whole idea of passkeys provided by an online platform should have been ruled out by the specification. It completely defeats the purpose of passkeys which is that the user has everything they need to authenticate themself.
