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 always thought of passkeys as a convenient way to authenticate.
I am password-less on multiple services.
I have an authentication app on my phone that authenticate me when I am away of my computers. I have passkeys on my personal computer and another set of passkeys on my work laptop.
If I have to authenticate from your computer I simply use my auth app, click on “it’s a public computer” and I am good to go.
