Obtaining a Digital PKI Certificate

The DoD Public Key Infrastructure/Enabling (PKI) certificate is normally located in the chip on your Common Access Card (CAC). This certificate is used by DBsign to verify your identity and authority to use DTS. Because of this, a CAC reader is currently required to access DTS. To load these certificates from your CAC, certain brands of CAC readers will also require an updated installation of "ActivClient" or similar program provided by your IT Department. For issues regarding the PKI certificates on your CAC, please contact your local CAC Issuance Office.

In certain cases, the PKI certificate can be provided as a file. PKI files located on your computer will not require a CAC reader. For any issues regarding certificate files, please contact your Local Registration Authority.

Contact Your DTA About Your DTS Account

Once you've made the necessary changes to your web browser and have obtained a digital PKI certificate, you may access DTS. After clicking the Log In button, you may be prompted to enter and confirm your SSN for security purposes. If this is your first time accessing DTS, you'll receive a message indicating that your SSN does not match any existing profiles and that you must use the self-registration system to continue. Please contact your DTA to ensure that you enter the correct organizational information.

If your profile still needs to be associated to your new or current organization, you'll receive an error message that your account can not be found or has been locked. Please contact your DTA to activate your profile. DTS account creation is normally done during the check-in process when reporting to a new organization.
