Explainer
https://github.com/bobomb/MSEdgeExplainers/blob/9838480febdc51033b46e2d9d7a9d1813df890f1/WebAuthnRemoteClientDataJSON/explainer.md


Specification
https://github.com/w3c/webauthn/pull/2375


Summary
Allows a caller to provide a complete clientDataJSON string for a WebAuthn 
ceremony, which the browser passes through to the authenticator without 
modification. This enables remote desktop web clients to forward WebAuthn 
requests with the exact clientDataJSON from the remote host, preventing 
signature verification failures caused by differences between the 
browser-constructed and host-provided clientDataJSON.


Blink component
Blink>WebAuthentication


Web Feature ID
webauthn


Motivation
The remoteClientDataJSON extension for the Web Authentication API allows a 
caller to provide a complete clientDataJSON string for a WebAuthn ceremony, 
which the browser passes through to the authenticator without modification. 
This enables remote desktop web clients to forward WebAuthn requests with the 
exact clientDataJSON from the remote host, preventing signature verification 
failures caused by differences between the browser-constructed and 
host-provided clientDataJSON.
