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...
Do you add separate keys on every device?
If you do, how long does it take you to add a new device?
For example, when you login on Github, go in your settings, authentication & security on the left.
Click “add passkey”, enter your Windows Hello PIN, click save.
It will ask you to enter a name, so I go with ComputerName-GitHub
Click ok.
Done with this device.
How long does it take? Well, how fast can you do these steps?
