Refinements to “OAuth 2.0 Demonstration of Proof-of-Possession at the Application Layer (DPoP)”

OAuth logoA number of refinements have been applied to the DPoP specification. As recorded in the History entries, they are:

  • Editorial updates
  • Attempt to more formally define the DPoP Authorization header scheme
  • Define the 401/WWW-Authenticate challenge
  • Added invalid_dpop_proof error code for DPoP errors in token request
  • Fixed up and added to the IANA section
  • Added dpop_signing_alg_values_supported authorization server metadata
  • Moved the Acknowledgements into an Appendix and added a bunch of names (best effort)

Thanks to Brian Campbell for doing the editing for this round.

The specification is available at:
