Title: OAuth 2.0 Step Up Authentication Challenge Protocol Author: V. Bertocci, B. Campbell Status: Standards Track Stream: IETF Date: September 2023 Mailbox: vitto...@auth0.com, bcampb...@pingidentity.com Pages: 14 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-oauth-step-up-authn-challenge-17.txt URL: https://www.rfc-editor.org/info/rfc9470 DOI: 10.17487/RFC9470 It is not uncommon for resource servers to require different authentication strengths or recentness according to the characteristics of a request. This document introduces a mechanism that resource servers can use to signal to a client that the authentication event associated with the access token of the current request does not meet its authentication requirements and, further, how to meet them. This document also codifies a mechanism for a client to request that an authorization server achieve a specific authentication strength or recentness when processing an authorization request. This document is a product of the Web Authorization Protocol Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
