Challenge-response with asymmetric encryption is pretty much perfect. I wish all auth worked like SSH.
Passkeys kind of take that concept, but make it suck. No backups. Terrible interoperability.
The other day I attempted to create one on my Mac with Firefox. The system passkey popup came up and made me scan a QR code with my iPhone that had to be connected to the internet. Bitwarden (my iOS passkey manager, that part works well) did open, but after selecting the profile to create the passkey in, it errored out. No passkey for me.
