Standards Track [Page 2] RFC 8176 Authentication Method Reference Values June 2017 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 password and OTP authentication methods were used. The definition of particular values to be used in the "amr" Claim is beyond the scope of this specification. Parties using this claim will need to agree upon the meanings of the values used, which may be context-specific. The "amr" value is an array of case sensitiveShow full document text
