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...
For me, I’d prefer that everyone just adds biometric authentication techniques. A couple websites do this already and it’s great. Many devices have biometrics built in already and if this was widespread I’d certainly have no problem buying a fingerprint reader for my desktop computer.
That’s literally a passkey.
