JSON Web Token (JWT) Profile for OAuth 2.0 Access Tokens
draft-ietf-oauth-access-token-jwt-11
Abstract
This specification defines a profile for issuing OAuth 2.0 access
tokens in JSON web token (JWT) format. Authorization servers and
resource servers from different vendors can leverage this profile to
issue and consume access tokens in interoperable manner.

1. Introduction
The original OAuth 2.0 Authorization Framework [RFC6749]
specification does not mandate any specific format for access tokens.
While that remains perfectly appropriate for many important
scenarios, in-market use has shown that many commercial OAuth 2.0
implementations elected to issue access tokens using a format that
can be parsed and validated by resource servers directly, without
further authorization server involvement. The approach is
particularly common in topologies where the authorization server and
resource server are not co-located, are not run by the same entity,
or are otherwise separated by some boundary. At the time of writing,
many commercial implementations leverage the JSON Web Tokens (JWT)
[RFC7519] format.
Many vendor specific JWT access tokens share the same functional
layout, using JWT claims to convey the information needed to support
