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.

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.

 three-week review period on the mailing list,
 on the advice of one or more Designated Experts.
