The OAuth 2.0 Dynamic Client Registration Protocol specification is now RFC 7591 – an IETF standard. The abstract describes it as follows:
This specification defines mechanisms for dynamically registering OAuth 2.0 clients with authorization servers. Registration requests send a set of desired client metadata values to the authorization server. The resulting registration responses return a client identifier to use at the authorization server and the client metadata values registered for the client. The client can then use this registration information to communicate with the authorization server using the OAuth 2.0 protocol. This specification also defines a set of common client metadata fields and values for clients to use during registration.
This specification extracts the subset of the dynamic client registration functionality defined by OpenID Connect Dynamic Client Registration 1.0 that is applicable to any OAuth 2.0 deployment. It is intentionally completely compatible with the OpenID Connect registration spec, yet is also now usable as a basis for dynamic client registration by other OAuth 2.0 profiles.
My personal thanks to Justin Richer, John Bradley, Maciej Machulak, Phil Hunt, and Nat Sakimura for their work on this specification and its precursors. Thanks also to members of the OpenID Connect working group and members of the OAuth working group, as well as its chairs, area directors, and other IETF members who contributed to this specification.
