NIST SP 800-63-4: Digital Identity Guidelines | Second Public Draft
The second public drafts of revision 4 of NIST Special Publications 800-63, 800-63A, 800-63B, and 800-63C are now available, with comments due October 7, 2024.
The rapid proliferation of online services over the past few years has heightened the need for reliable, equitable, secure, and privacy-protective digital identity solutions. Revision 4 of NIST’s Special Publication (SP) 800-63, Digital Identity Guidelines, responds to the changing digital landscape that has emerged since the last major revision of this suite was published in 2017—including the real-world implications of online risks. The guidelines present the process and technical requirements for meeting digital identity management assurance levels for identity proofing, authentication, and federation, including requirements for security and privacy as well as considerations for fostering equity and the usability of digital identity solutions and technology.
