Beginning March 8th, 2021, you will be able to us GSA’s FAS ID to log in to eOffer/eMod, and will no longer need digital certificates to access these applications.

FAS ID is a secure, centralized identity management system that allows you to access many GSA applications with a single 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, there’s no need to register again. If you don’t have an established FAS ID already, simply follow the steps outlined in eOffer and register for an account starting on March 8, 2021. For technical support with eOffer and eMod, contact the eOffer/eMod Help Desk at 1-866 472-9114 or
