Explainer

https://github.com/w3c/webauthn/wiki/Explainer:-JSON-Serialization-Methods

Specification

https://w3c.github.io/webauthn/#publickeycredential

Summary

The WebAuthn PublicKeyCredential.toJSON(), parseCreationOptionsFromJSON() and parseRequestOptionsFromJSON() methods let developers serialize a WebAuthn response into a JSON object or deserialize a WebAuthn request object from its JSON representation.

Blink component

Blink>WebAuthentication

Motivation

Developers frequently complain that WebAuthn request and response objects cannot easily be serialized in order to pass them between a server and client in a HTTP request. We're therefore adding methods to the API that permit deserialization of WebAuthn requests from and serialization of responses to JSON.

Sounds good, thanks! Not needed for I2P, but for an upcoming I2S it would be good to have a link or two under "web developer signals" to back up the "developers frequentlyc complain" argument.
