The IESG has approved the following document: - 'Authentication Method Reference Values' (draft-ietf-oauth-amr-values-08.txt) as Proposed Standard This document is the product of the Web Authorization Protocol Working Group. The IESG contact persons are Kathleen Moriarty and Eric Rescorla. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-oauth-amr-values/ Technical Summary The "amr" (Authentication Methods References) claim is defined and registered in the IANA "JSON Web Token Claims" registry but no standard Authentication Method Reference values are currently defined. This specification establishes a registry for Authentication Method Reference values and defines an initial set of Authentication Method Reference values. Working Group Summary The working group had solid consensus, no issues. Document Quality A number of implementations exist and include: Implementations of the OpenID Mobile Authentication Profile, which is defined by the MODRNA working group, use “amr” values. This includes all the GSMA Mobile Connect deployments. Microsoft Azure Active Directory and Microsoft Active Directory Federation Services (ADFS) use “amr” values. Google’s identity provider uses “amr” values. There is one downref noted in the shepherd report and last call announcement: The following document is a non-IETF document that may require a downward reference: [OpenID.Core] Sakimura, N., Bradley, J., Jones, M., de Medeiros, B., and C.
