Common Access Card (CAC) Authorization

The DoD is in the process of changing the certificates that are on the Common Access Card (CAC). The CAC certificates that are available to login to CPARS are the following:

  • Identity (ID)
  • Signature (Email)
  • Authentication (PIV_Auth)

As of 31 July 2019, the ID and Email certificates will no longer be accepted and only the PIV_Auth certificate can be used to login to CPARS.

DoD Users: All CAC users that received their card before 24 February 2018 will need to activate the new PIV_Auth certificate. Instructions to activate the certificate or verify that it has been activated can be found on the Navy Infosec Website ( CAC users who received their card after 24 February 2018 should already have this certificate activated and no further action is needed.

Note that this only applies to CAC users. DoD ECA and Federal PIV certificates are unaffected by this change.

Browser/Software Compatibility

We recognize that our user may have various Internet Browsers. It is our goal to provide users with a modern and up-to-date experience on the CPARS system.

To access the CPARS applications, you will need to have access to the internet along with the following:

  • CPARS fully supports the latest three major desktop versions of Internet Explorer, and the latest major desktop version of Chrome, Firefox, and Safari. Older browsers may still view CPARS, however users should expect mixed results. A "major version" refers to a full numeric release, like 9.0 and 10.0 (not minor releases like 9.2.x and 10.2.x).
  • The Adobe Acrobat Reader should be installed. This allows you to view and print the PDF attachments in CPARS and FAPIIS. The reader can be downloaded and installed from Adobe Acrobat. If you have any problems downloading or installing the reader, please contact our Technical Support.

If you have any questions about our Browsers Compatibility Statement or Internet Compliant Standards, please contact us.
