NOTE: This article has been updated to reflect the fact that after adding the new digital certificates, you should not remove the existing root and intermediate certificates.

We’re renewing the digital certificates for our system-to-system (S2S), application programming interface (API)-based integrations on March 12, 2022 in the non-production and production customer test environments (CTE) and on April 16, 2022 in the production environment.

The impacted URLs include:

Which integrations are impacted? 

  • Any lender that needs to update the Trust store to new root and intermediate certificates
  • Any lender using a S2S interface to one of these Loan Advisor applications that is implemented with a one-way SSL that is not hosted by a software partner
  • Any integrated partner (lender or software provider) that has built to Freddie Mac applications AND implemented a one-way SSL

What if this impacts my implementation? (UPDATED)

To avoid service interruption, please update your Trust Store as needed with the appropriate digital certificates on or before March 12 (for CTE) and on or before April 16 (for production) wherever the S2S interface is hosted/installed.  Please do not remove the existing root and intermediate certificate.

Why are we updating digital certificates again?

Best practices dictate that we renew our digital certificates annually. To make this process as seamless as possible for our clients, we align our digital certificate renewals so they occur at the same time each year.

Please review these updates with your information technology (IT) or information security (InfoSec) administrators to determine if your organization is impacted and, if so, please take the steps provided. While your IT group should be able to assist in making any required changes, if you have further questions don’t hesitate to contact your Freddie Mac representative or the Customer Support Contact Center (800-FREDDIE) – we’re here to help.
