MCW Accounts
MCW Account Overview  

MCW accounts are used across the MCEN for access to various platforms.  This page discusses MCW accounts as they pertain to access to HQMC C4 Cybersecurity sites.

MCCAST Accounts  

The Marine Corps Compliance and Authorization Support Tool (MCCAST) uses MCW accounts for access and are managed by the USMC Assessment and Authorization Team.  For access to the MCCAST, visit the " A&A POC" section located to the right in order to submit a trouble ticket.  

SharePoint Accounts  

MCW accounts are used for EIS SharePoint Site access and are managed by the EIS Helpdesk. Access to  individual SharePoint sites are managed by the respective SharePoint Site Collection Administrators. To request access perform the steps below:

1. Check for existing account:  

  • Does "I:0#.w/mcw\" or "mcw\" precedes the user name? Then an MCW account exists. Contact the Cybersecurity Division Information Manager to request access using the contact link to the right.   
  • If an error stating, "Your session could not be established", is displayed, then an account does not exist - proceed to number two (2) below to submit an account creation request.

2. Submit account creation requests here: MCEITS Home


  • List the reason for the access request.   
  • Select "HQMC C4" to notify the corresponding site collection administrators.
