Authentication Method Reference Values
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.

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 sensitive
