[Openid-specs-ab] Is anyone implementing OIDC4VP uses the option to embed VP inside the ID Token?

[Kristina Yasuda]

Hi All,

When we had an initial discussion designing what is now OpenID Connect for Verifiable Presentations (OIDC4VP) draft, we left two options how to embed Verifiable Presentation in the response:

  *   embedding inside the ID Token or Userinfo response
  *   return as a newly defined "VP Token" which is provided alongside an ID Token

With several implementations of OIDC4VP draft emerging, implementors seem to be preferring the second VP Token option considering it to be simpler and clearer.

Please let us know if you are implementing or considering implementing OIDC4VP using the option to embed a VP inside an ID Token. From the interoperability perspective, I think it would be preferrable if we can make a choice and converge around one option. (Some discussion happened at 2021-11-22 Connect call)

Kindest Regards,
Kristina
