Windows exposes APIs for "windows hello" - which is an easy way for apps to authenticate via usb authenticators or windows' built-in authenticator (when available via TPM). I imagine that, on macOS, such an API would allow apps to authenticate using any passkeys in iCloud Keychain directly, of course with an OS-based user presence requirement like entering system password or using touch ID.
