To get started you will need:

  • CAC
  • Card reader
  • Middleware (if necessary, depending on your operating system version)

You can get started using your CAC by following these basic steps:

  1. Get a card reader.
    At this time, the best advice for obtaining a card reader is to work with your home component to get one. In addition, please review the DoD CAC Reader Specifications for more information regarding the requirements for a card reader.
  2. Install middleware, if necessary.
    You may need additional middleware, depending on the operating system you use. Please contact your CC/S/A for more information on the middlew​are requirements for your organization. You can find their contact information on our Contact Us tab.
  3. Install DoD root certificates with InstallRoot 5.2 (32-bit, 64-bit or Non Administrator).PKI-PKE Lock
    In order for your machine to recognize your CAC certificates and DoD websites as trusted, run the InstallRoot utility (32-bit, 64-bit or Non Administrator) to install the DoD CA certificates on Microsoft operating systems. If you're running an alternate operating system such as Mac OS or Linux, you can import certificates from the PKCS 7 bundle. The InstallRoot User Guide is available here.

  4. Make certificates available to your operating system and/or browser, if necessary.
    Pick your browser for specific instructions.
