DoD CAC Login Assistance

Q: I have a DOD CAC. Does that automatically grant me access to login to DAU or do I still need to request an account? 

A: Please see the information below.

  • If you are a new Defense Acquisition Workforce member or if you are a new federal employee for DoDEA, DMA, or DTRA, an account will be created for you automatically.
  • All other DoD CAC holders must request an account by submitting the SAAR in order to login to DAU. NOTE: If you attempt to login with your CAC before an account has been created, you will receive a CAC login error. 

Q: I'm receiving an error message when trying to login with my DoD CAC. Why is this occurring?

A: Multiple factors can impact your ability to login to DAU with your DoD CAC. If you receive one of the errors below, please follow the troubleshooting guidance to address this issue. Note: The immediate workaround to access your account is to login with your Username and Password.
