RFC 7519: JSON Web Token

tools.ietf.org/html/rfc7519

JSON Web Token (JWT, RFC 7519) is a way to encode claims in a JSON document that is then signed.

JWTs can be used as OAuth 2.0 Bearer Tokens to encode all relevant parts of an access token into the access token itself instead of having to store them in a database.
