                     draft-ietf-oauth-amr-values-04

Abstract

   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.

1.  Introduction

   The "amr" (Authentication Methods References) claim is defined and
   registered in the IANA "JSON Web Token Claims" registry
   [IANA.JWT.Claims] 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.

   For context, the "amr" (Authentication Methods References) claim is
   defined by Section 2 of the OpenID Connect Core 1.0 specification
   [OpenID.Core] as follows:

   amr
      OPTIONAL.  Authentication Methods References.  JSON array of
      strings that are identifiers for authentication methods used in
      the authentication.  For instance, values might indicate that both
