Do I Need a CAC for DTS?

DTS access requirements have gotten complicated with all the authentication options and policy variations flying around. As someone who has helped many navigate defense travel systems, I learned everything there is to know about what credentials you need. Today, I will share it all with you.

Short Answer

Probably should have led with this section, honestly. For most DoD users, CAC authentication is required for Defense Travel System access. Alternatives exist but CAC is standard.

Why CAC?

That’s what makes CAC preferred—it provides strong two-factor authentication that meets DoD security requirements for systems handling travel orders and financial data.

Exceptions

Some users may have alternative authentication options. Check with your organization’s travel administrator for specific requirements.

Setup

Ensure your CAC reader works and certificates are properly installed before attempting DTS access.
