Thanks for your cool slide.

I'm not sure what  is the “public key seed”  in your slide. It seems that main key need to store or generate "recovery credential id" which equivalent to WebAuthn Credential ID.

extensions: {
  “recovery”: {
    “action”: “generate”

extensionOutputs: { 
  “recovery”: {
    “action”: “generate”,
    “state”: 3,
    “creds”: [{
      “id”: “ABCD…”, //equivalent to WebAuthn credentialId
      “publicKey”: “AAAA…”


How to be generated creds.id and creds.publicKey from "public key seed" in main authenticator? or just 
be stored creds.id and creds.publicKey from recovery auhenticator?
