The OpenID Foundation has launched a new working group - the Digital Credentials Harmonized Presentation Working Group (DCHP WG).

The new DCHP WG supports a joint initiative between experts of ISO/IEC JTC1/SC 17 (ISO) WG10 and WG4 and the OpenID Foundation’s Digital Credentials Protocols Working Group (DCP WG) to harmonize their credential presentation protocols. 

Today, ISO/IEC 18013-7 Device Request/Device Response and OpenID for Verifiable Presentations (OID4VP) Authorization Request/Authorization Response take different approaches to credential presentation. The DCHP WG will develop a technical specification for a harmonized Digital Credentials Request Protocol that brings these together, and supports the exchange of multiple credential formats (mdoc and SD-JWT VC). 

The group's charter was mutually agreed by experts from both working groups and sets out its purpose, scope, and method of work in full. This charter has been approved by the Specifications Council in line with the OIDF Process Document.

As the specification is intended for adoption by both ISO WG10 and the OpenID Foundation’s DCP WG, the DCHP WG will follow agreed Working Procedures designed to achieve this goal. 

First meeting and how to participate

The first DCHP WG meeting takes place on Monday 29 June 2026, 6am to 9am PT. Those interested in joining will find the Zoom link on the DCHP WG page.

To follow progress and connect with working group members, please join the mailing list by contacting openid-specs-dchp@lists.openid.net.

In order to contribute to a specification within the working group, an Intellectual Property Rights (IPR) contribution agreement can be submitted, either electronically or by paper by selecting “All WGs” or just the “DCHP WG.” 

About the OpenID Foundation

The OpenID Foundation (OIDF) is a global open standards body committed to helping people assert their identity wherever they choose. Founded in 2007, we are a community of technical experts leading the creation of open identity standards that are secure, interoperable, and privacy-preserving. The Foundation’s OpenID Connect standard is now used by billions of people across millions of applications. In the last five years, OAuth2 - the FAPI standard for interoperable, high security - has become the standard of choice for Open Banking and Open Data implementations, allowing people to access and share data across entities. Today, the OpenID Foundation’s standards are the connective tissue that enable people to assert their identity and access their data at scale, the scale of the internet, enabling “networks of networks” to interoperate globally. Individuals, companies, governments and non-profits are encouraged to join or participate. Find out more at openid.net.
