Salesforce by default dispatches an email 60 days, 30 days, and 10 days prior to the certificate's expiration date. The email will look similar to the message below.

You have one or more certificates in your Salesforce org Company Name Organization ID that will expire soon. Review the list below and visit Certificate and Key Management from Setup to make an update.

2. In the Quick Find box, located on the left-hand side, type Certificate and click Certificate and Key Management.
   
3. Click the Create Self Signed Certificate button and go through the steps for creating a new certificate.
   
4. Once the certificate has been created, type Single Sign-On Settings in the Quick Find/Search bar.
5. Under the SAML Single Sign-On Settings section, click Edit next to the Single Sign-On name and change the Request Signing Certificate to the newly created certificate from the drop-down menu. Click Save. Depending on your SSO setup, you may need to complete this step multiple times.
