Platform Notes
- The authenticatorAttachment property of responses, planned for specification delivery in WebAuthn L3, is not currently available in responses to

when using the platform authenticator or a hardware security key. It is supplied during credential creation, or when using FIDO Cross-Device Authentication for an authentication ceremony.
Cross-Device Authentication
Starting in Windows 11 version 23H2, FIDO Cross-Device Authentication (CDA) is supported globally at the operating system level and available for all apps and browsers. Persistent linking is available between Android devices (authenticator) and Windows 11 23H2+. iOS and iPadOS do not support persistent linking.
In Windows versions prior to 11 23H2, including Windows 10, support for FIDO Cross-Device Authentication (CDA) is only available in Chrome and Edge. It is not available globally. Persistent linking is available between Android devices (authenticator) and Chrome and Edge (clients) on these versions. iOS and iPadOS do not support persistent linking.
