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’m sorry but I seriously do not see any benefits to using passkeys.
I use 24 character passwords in Bitwarden with 2fa on all accounts, how is a passkey better than that?
