SUPPLEMENTARY INFORMATION: FIPS 201 establishes a standard for a 
Personal Identity Verification (PIV) system (Standard) that meets the 
control and security objectives of Homeland Security Presidential 
Directive-12 (HSPD-12). It is based on secure and reliable forms of 
identity credentials issued by the Federal Government to its employees 
and contractors. These credentials are used by mechanisms that 
authenticate individuals who require access to federally controlled 
facilities, information systems, and applications. This Standard 
addresses requirements for initial identity proofing, infrastructure to 
support interoperability of identity credentials, and accreditation of 
organizations issuing PIV credentials.
    FIPS 201 was issued on 2005 (70 FR 17975) in response to HSPD-12. 
Subsequent revisions included FIPS 201-1, published in 2006 and FIPS 
201-2 (version in effect), published in 2013 (78 FR 54626). In 
consideration of technological advancements over the last five years 
and specific requests for changes from United States Government (USG) 
stakeholders, NIST determined that a third revision of FIPS 201 was 
warranted. NIST received numerous change requests, some of which, after 
analysis and coordination with the Office of Management and Budget 
(OMB) and USG stakeholders, were incorporated in a proposed draft of 
FIPS 201-3. Other change requests incorporated in the draft resulted 
from the 2019 Business Requirements Meeting held at NIST. The meeting 
focused on business requirements of Federal departments and agencies. 
On November 3, 2020, a notice was published in the Federal Register (85 
FR 69599), soliciting public comments on the draft FIPS 201-3. During 
the public comment period, a virtual public workshop was hosted by NIST 
on December 9, 2020.
    The scope of changes reflected in FIPS 201-3 include the following:
    <bullet> Alignment with current NIST technical guidelines on 
identity management, OMB policy guidelines, and changes in 
commercially-available technologies and services.
    <bullet> Accommodation of additional types of authenticators 
through an expanded definition of Derived PIV credentials.
    <bullet> Focus on the use of federation to facilitate 
interoperability and interagency trust.
    <bullet> Addition of supervised remote identity proofing processes.
    <bullet> Removal of previously deprecated Cardholder Unique 
Identifier (CHUID) authentication mechanism and deprecation of the 
symmetric card authentication key and visual authentication mechanisms 
(VIS).
    <bullet> Support for secure messaging authentication mechanism (SM-
AUTH).
    Comments and questions regarding the draft were submitted by USG 
organizations, private sector organizations, and private individuals. 
NIST made several changes to the draft FIPS 201-3 based on the public 
comments received.
    Many commenters asked for clarification of the text of the Standard 
and/or recommended editorial and/or formatting changes. Other 
commenters suggested modifying the requirements and asked questions 
concerning the implementation of the Standard. All of the suggestions, 
questions, and recommendations within the scope of this FIPS were 
carefully reviewed, and changes were made to the Standard, where 
appropriate. Some commenters submitted questions or raised issues that 
were related but outside the scope of this FIPS. Comments that were 
outside the scope of this FIPS, but that were within the scope of one 
of the related Special Publications, were deferred for later 
consideration in the context of the revisions to these Special 
Publications. The disposition of each comment that was received has 
been provided along with the comments at https://csrc.nist.gov.
    The following is a summary and analysis of the comments received 
during the public comment period, and NIST's responses to them:
    1. Comment: Some commenters inquired about the effective date of 
the Standard. Commenters also inquired about the implementation 
schedule associated with the changes introduced in the Standard, once 
the Standard is in effect.

[[Page 3503]]

    Response: FIPS 201-3 will be effective immediately upon final 
publication, superseding FIPS 201-2. The effective date of new and 
updated features depends upon the release of revised NIST Special 
Publications or the release of new NIST Special Publications that will 
be developed following the publication of this Standard. The 
implementation schedule may be reflected in NIST's Special Publications 
or may be provided separately by OMB, as appropriate.
    2. Comment: Multiple commenters asked for clarification of the 
terms PIV account and enrollment records.
    Response: New terminology was introduced to define PIV identity 
account rather than PIV account. The PIV identity account is the 
cardholder's identity account for PIV credentials including derived PIV 
credentials. It includes stored or linked contents of enrollment 
records.
    3. Comment: There were multiple commenters who asked for guidance 
on biometrics and their use in PIV lifecycle processes. The comments 
related to the type of the biometrics on cards and how long the 
biometrics were valid.
    Response: FIPS 201-3 expands the use of optional biometric 
modalities (e.g., iris) for issuance and maintenance. The Standard also 
defines the use of automated facial comparison algorithm as a biometric 
modality. The Standard maintains the 12-year maximum lifetime for 
biometrics since studies show that the biometric can be matched for 
that length of time.
    4. Comment: Multiple commenters had concerns about the requirements 
for validating identity source documents and the requirements for REAL-
ID driver's licenses.
    Response: NIST emphasized that there are existing requirements to 
validate identity source documents to be genuine, authentic and 
unexpired. REAL-ID compliance requirements are clarified by referring 
to DHS's enforcement guidance.
    5. Comment: Commenters had concerns about the supervised remote 
identity proofing processes introduced in the draft FIPS 201-3. Some 
commenters sought greater allowances for remote proofing such as 
unstaffed stations. Clarification was sought on the intended use of the 
process, requirements for staff at remote sites and the protections 
applied to remote stations.
    Response: The Standard emphasizes the need for a staff to maintain 
the same level of assurance as in-person processes and to perform 
sensitive protection and maintenance activities at remote station.
    6. Comment: Several commenters requested detailed instructions on 
reporting card termination.
    Response: The Standard was updated to reflect termination in the 
card management system and in enrollment records.
    7. Comment: Several commenters requested changes on the management 
of derived PIV credentials.
    Response: The Standard clarifies processes and terms regarding the 
issuance or binding of derived PIV credentials to PIV identity 
accounts. The updates to the Standard include requirements and guidance 
on re-issuance and post-issuance management of Public Key 
Infrastructure (PKI) and non-PKI derived PIV credentials.
    8. Comment: Some commenters asked that FIPS 201-3 include periodic 
privacy impact assessments on all PIV related systems.
    Response: The Standard was updated to require periodic review of 
Privacy Impact Assessment.
    9. Comment: Several commenters raised concerns related to the 
requirement for the PIV Card to enforce a blacklist of disallowed PINs. 
They did not feel the technology was available to enable cards to 
maintain the blacklist and to provide automated enforcement of selected 
PINs.
    Response: The Standard removed the requirement due to the 
complexity of enforcing a blacklist by the PIV Card. Instead, the 
Standard specifies that the card holder be guided to select a strong 
PIN that is not easily guessable or commonly used.
    10. Comment: Some commenters asked to maintain use of the magnetic 
stripe and not deprecate it in this version of the Standard.
    Responses: NIST confirmed the deprecation of the magnetic stripe in 
this version of the Standard with potential removal in a future 
revision. Use of the magnetic stripe is still allowed during the 
deprecation phase but it should begin to be phased out.
    11. Comment: Some commenters had concerns on the removal of Legacy 
PKI. Some commenters asked NIST to clarify how a cross-certified PKI 
will operate as agencies transition away from Legacy PKI 
implementations. Others asked that Legacy PKI use to remain in the 
Standard.
    Response: The Standard was revised to allow departments and 
agencies that operate their own PKIs to issue digital signature and key 
management certificates according to agency-specified certificate 
policies as an alternative to the Federal PKI Common Policy Framework 
policies referenced by FIPS 201-3. To facilitate greater 
interoperability and consistency of issuance practices across agencies, 
the next revision of FIPS 201 will require the use of the specified 
FPKI policies.
    12. Comment: Several commenters asked to either reconsider removal 
of the CHUID authentication mechanism or clarify the effective date.
    Response: The CHUID authentication mechanism was deprecated in the 
prior revision of the Standard and is designated for removal in this 
revision. NIST concluded that removal of CHUID authentication is 
necessary at this time and will become effective when this version of 
the Standard is approved. OMB will provide additional implementation 
guidance as necessary.
    13. Comment: A few commenters asked that SYM-CAK not be deprecated 
because it is still supported in some implementations.
    Response: Even though SYM-CAK has been deprecated in this version, 
its use is not prohibited. However, support will be removed in the next 
revision of the Standard.
    14. Comment: Commenters indicated that the Physical Assurance Level 
(PAL) concept for facility access was not consistent with assurance 
levels in NIST SP 800-63B.
    Response: The Authenticator Assurance Levels (AAL) described in 
NIST SP 800-63B are specific to network-based authentication, not 
authentication for facility access. As a result, the final version of 
the Standard has removed the concept of PAL and disassociated assurance 
levels from NIST SP 800-63-B for facility access. Instead, 
authentication mechanisms are described independently from SP 800-63B 
for facility access.
    15. Comment: Multiple commenters expressed concern that the 
description of assurance levels for logical access at local 
workstations was not consistent with the AALs defined in NIST SP 800-
63B.
    Response: The AALs described in NIST SP 800-63B are specified for 
network-based authentication, not local authentication to workstations. 
As such, the final version of the Standard describes assurance levels 
for logical access to local workstations independently from the SP 800-
63B-defined AALs.
    16. Comment: Several commenters asked for a more detailed 
description of the operation of Federated IdPs.
    Response: IdP terminology was updated to better align with the rest 
of the document. Secure operation of IdPs will be covered by updates to 
SP 800-79.
    17. Comment: A commenter asked that the use of stable identifiers 
be

[[Page 3504]]

included in FIPS 201-3 to support interoperability among federal 
agencies.
    Response: The new Special Publication for Federation, SP 800-217, 
will describe processes for linking PIV identity accounts to relying 
party services in interoperable and extensible manners.
    18. Comment: A commenter asked that there be a discussion about the 
direct use and the federated use of PIV credentials.
    Response: The Standard explains both the direct and the federated 
use of PIV credentials. Of the two approaches, the Standard recommends 
the use of federation protocol as the primary means to accept and 
process PIV credentials from other agencies.
