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/ 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passkey on Safari on macOS 15.5, but Typage doesn't work with a YubiKey 5, so there is some support (the MDN data is out of date) but also something weird.
