The JWT [RFC7519] "amr" (Authentication Methods References) claim [OpenID.Core] contains values conveying authentication methods used in the authentication. They are registered in the IANA "Authentication Method Reference Values" registry [IANA.AMR].¶
Since the Authentication Method Reference Values [RFC8176] specification was published, several new authentication methods have been developed and/or come into widespread use. This specification defines additional Authentication Method Reference values to represent these additional authentication methods in use today.¶
While these Authentication Method Reference values are general purpose and can be used in any JSON Web Token (JWT) [RFC7519], one use case for them is use in KYAPay tokens [I-D.skyfire-oauth-kyapay-token].¶
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.¶
The following Authentication Method Reference values are defined by this specification:¶
Authenticator App (e.g., Okta Verify, Google Authenticator, Microsoft Authenticator)¶
In-person Authentication¶
Video Authentication (live video interview)¶
Background Authentication (Silent network authentication of phone number, device recognition, geo-location, etc.)¶
Use of code or link sent to e-mail¶
Push notification to mobile phone¶
The security considerations defined in Authentication Method Reference Values [RFC8176] apply to this specification.¶
The privacy considerations defined in Authentication Method Reference Values [RFC8176] apply to this specification.¶
This specification registers the following Authentication Method Reference values in the IANA "Authentication Method Reference Values" registry [IANA.AMR] established by [RFC8176].¶
