Common Access Cards (CAC)
Most .mil websites that require login use CAC as their primary method if identity verification. When accessing these websites, users should use their normal CAC certificate vice their EMAIL certificate. Known exceptions to this are the Navy Reserve Homeport and any Outlook Web Access (OWA) email system. For amplifying information about CAC, refer to the official DoD CAC website here.
MilitaryCAC offers a wide range of support for users needing assistance in using their CAC for all services. Highlighted pages include the support pages for using CAC on Windows 10, macOS, and Linux. Users needing further assistance can easily get help here.
