How do I register my CAC with AKO/DKO?

In order to register your CAC to your AKO account, you must:

  • Be at a computer where you can put your CAC in the CAC reader, and the CAC software is correctly installed.
  • Have an active AKO/DKO Account.
  • Know your CAC Pin.
  • Know your AKO/DKO Password (if registering from inside the portal.)

There are two ways to register your CAC with your account. The following steps will guide you through registering your CAC with your AKO/DKO Account.

The first and easiest option is to register your account from the AKO/DKO Login page.

  1. Insert your CAC into the reader.
  2. Make your certificates available to Windows, which can be done in the CAC software on your computer. Reference Answer ID 265 for how to do this.
  3. Click the CAC Login button.
  4. Enter your CAC PIN when prompted.
  5. You will then be logged into your account and your CAC will be registered.

If you are having difficulty registering your CAC from the login page, you will need to log into your account with your username password and follow the below steps.

  1. Log into your AKO account with your username and password (do not press the CAC login button.) If you need a password for your AKO/DKO account, please Click Here (259) for instructions on how to reset your password.
  2. Place your CAC into the CAC reader.
  3. Make your certificates available to Windows, which can be done in the CAC software on your computer. Reference Answer ID 265 for how to do this.
  4. Go to the “My Account” in the toolbar on the AKO/DKO homepage. Click on “Login Options”, and then click on “CAC / Cert Registration.” If you have an Email Only account, click on “CAC / Cert Registration” located on the right side of the page.
  5. If you see a screen which says: ‘”Current Registered Information”, then a CAC is already registered to this account. You can clear the information with the “Clear Registered Information” button. If the screen says you’re not currently registered, click the “Register” button.
  6. At this point, it may ask you to do any of the following tasks:
  • If it asks you to choose a digital certificate, choose a certificate with your name.
  • If it asks for your Active Client PIN, enter your PIN associated with your CAC – this is the number issued to you at the CAC office when you received your CAC.
  • If it asks for your AKO password, enter your current AKO/DKO password.

You should now see a screen which indicates that you have succesfully registered your CAC.
