Why do I need an account?

In order to register and use any extranet application/course, you must first have a APHC extranet account. Once an extranet account has been created, you will then be able to register for the desired course/application.

The Course Registration (CREG) Application directs users to the APHC Extranet whenever they select one of the following links on a course’s Course Details page:

  • The Apply link.
  • The Add name to Course interest list link.

An account (With valid CAC or Username/Password) is required to access this site.

Help for logging on with CAC

There may be cases where the CAC account is not associated with your account, it is locked, or it is disabled. These instructions give solutions to the issues as needed:

  • If you have a Username and Password that the CAC account is not associated with, you will receive a message "This CAC cannot be used to login".
    1. You have the option to login with a Username and Password and associate your CAC account in the Edit profile page from the 'Select Action' dropdown.
    2. You have the option to click the link 'Don't have an account yet? Register for one now'. At this point, you will need to select an application and click on the 'Register with a CAC' box. Then, enter the email address and follow the procedures.
  • If you receive the message 'Your CAC account is locked'.
    1. You have the ability to contact the proponent and have them unlock your account for you.
