March 8th Transition to GSA FAS ID for eOffer and eMod

Attention MAS contract holders: 

As of March 8, 2021, contractors will use FAS ID to access eOffer and eMod

FAS ID is a secure, centralized identity management system that allows contractors to access many GSA applications with one email and password. FAS ID was created as part of our overall IT modernization effort and has already been implemented on the FAS Sales Reporting Portal (SRP), GSA Advantage Purchase Order Portal, GSA Vendor Portal, the Mass Mod Portal, and eBuy. If you already have an established FAS ID login for one of these systems and currently have access to GSA’s eOffer/eMod, you do not need to register again. Users without an established GSA FAS ID will need to follow the steps outlined in the system and register for an account starting on March 8, 2021. 


IMPORTANT: Contractors and offerors will not be able to access eOffer and eMod March 6 through March 7, 2021 as we transition to FAS ID.  Please plan ahead to ensure you do not need to access eOffer/eMod during the transition period. 


Please note: Digital certificates will no longer be required to access eOffer and eMod once we have transitioned to FAS ID! While digital certificates won’t be needed for these applications after the transition, contractors may still need to maintain their digital certificates for other government and non-goverment customers. Contractors with expiring(ed) digital certificates who will not need to modify their contract or sign a new offer may decide it in their best interest to forgo the expense of purchasing/renewing their digital certificates until the FAS ID transition is complete.
