Nearly all of us were affected by OPM's data breach where they revealed social security numbers and finger prints of some 21.5 million individuals due to inadequate security on their network. As a result of this data breach, they provided credit monitoring services to affected individuals.
Recently, OPM announced that one of their providers will no longer provide services, and anyone using that provider will be allowed to switch to OPM's other provider. If you are covered by ID experts (My IDCare) there is no change to your current coverage and no action is required at this time. However, if you are covered by Winvale/CSID, your coverage will expire on December 1. You should receive a notification letter from OPM with a 25 digit PIN code that you will need to re-enroll with the new vendor. You should also receive an email from Winvale/CSID notifying you of the end of their coverage with OPM.
