I was waiting for the prf to be implemented since a long time exactly for this type of applications (e2e encryption), but , as usual, Safari doesn't support it

Huh, iCloud Keychain supports the prf extension when used with Chrome, so I had assumed they added support to Safari as well, but I just tested it and sure enough, you're right.

Edit: well https://webauthn-passkeys-prf-demo.explore.corbado.com/ works with an iCloud Keychain passkey on Safari on macOS 15.5, but Typage doesn't work with a YubiKey 5, so there is some support (the MDN data is out of date) but also something weird.

I'm pretty sure Safari supports it since iOS 18! See for example https://www.corbado.com/blog/ios-18-passkeys-automatic-passk... and https://www.corbado.com/blog/passkeys-prf-webauthn.
