Graduates of the SDSU Homeland Security program may request an @alum.hsec.sdsu.edu email forwarder. Your alumni email address will forward all email to an existing email account that you own. To clarify, you will not login to the alumni email address at all. The benefit is that you can maintain your affiliation with the SDSU HSEC program and enjoy the benefits of an .edu email address forwarded to your permanent email account (you will enter on the next screen).
The mailbox username is the part that appears in front of @alum.hsec.sdsu.edu. It is recommended that you use some variation of your name with optional periods. For example, firstname.lastname@example.org is the same as email@example.com -- Postmaster has final decision on usernames assigned.
