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...
But that is exactly what he recommends, using a password manager - with one time email authentication for the first login as an extra step, right?
He says:
but doesn’t talk about passkeys + password manager.
Nope.
Using a cross-platform password manager with synced passkeys is different and much more secure than using a password manager with email TOTPs or sign-in links with emails that aren’t end-to-end encrypted.
And password manager adoption is much higher than PGP keyserver adoption, and if you can’t discover someone’s public key you can’t use it to encrypt a message to them, so sending end-to-end encrypted emails with TOTPs/sign-on links isn’t a practical option.
According to Statista, 34% of Americans used password managers in 2023 (a huge increase from 21% in 2022), so it’s not even like the best case scenario is rare.
