> Apple more or less [enforces 2FA](https://support.apple.com/guide/security/secure-icloud-keychain-recovery-secdeb202947/web) for Keychain access to prevent such an attack on credentials from happening. But there are certainly cases where this threat model is not acceptable, e.g. under certain regulations (in their current form at least).

Apple have now officially confirmed to me, that they are not willing to support attested single device credentials on iOS16 or Ventura going forward, meaning that there is no way to "avoid" passkeys. You either need to attest credentials and reject passkeys and all apple platform authenticators, or you will need to accept passkeys and their risks.
