About DoD CAC

DoD CAC is an independent resource dedicated to helping military personnel, DoD civilians, and contractors navigate Common Access Card technology. We provide practical, tested guidance based on real-world experience with CAC systems.

Our Mission

The Common Access Card is essential for accessing DoD networks, signing documents, and encrypting communications. Unfortunately, official documentation can be scattered and technical. Our mission is to provide clear, step-by-step guidance that actually works—written by people who have solved these problems themselves.
