1. Introduction
JSON Web Token (JWT) [JWT] is a JSON-based [RFC7159] security token
encoding that enables identity and security information to be shared
across security domains. A security token is generally issued by an
Identity Provider and consumed by a Relying Party that relies on its
content to identify the token's subject for security-related
purposes.
The OAuth 2.0 Authorization Framework [RFC6749] provides a method for
making authenticated HTTP requests to a resource using an access
token. Access tokens are issued to third-party clients by an
authorization server (AS) with the (sometimes implicit) approval of
the resource owner. In OAuth, an authorization grant is an abstract
term used to describe intermediate credentials that represent the
resource owner authorization. An authorization grant is used by the
client to obtain an access token. Several authorization grant types
