Does my SAM registration expire? What do I need to do to keep it active?
SAM registration will expire 1 year from the LAST update. Independently there is a 6 month password expiration that happens and has nothing to do with the actual registration expiring. The SAM expiration date will change anytime you do an update in SAM (except password updates). At least 30 days prior to the SAM expiration, you will be notified to do an update. If your expiration is listed as February 3, 2016 and you do an update in September 2015, the 1 year clock on expiration will start over and a required update will not be needed again until September of 2016.
