To comply with the latest browser and security standards, enable and deploy enhanced domains. With enhanced domains, your company-specific My Domain name is included in the URLs that Salesforce hosts for your org. Consistent domain formats improve the user experience and standardize URLs for use in custom code and API calls. Also, with enhanced domains, your users can access Salesforce from browsers that block third-party cookies. Because this update affects application and login URLs, including Experience Cloud sites, Salesforce Sites, and Visualforce pages, we recommend that you deploy enhanced domains before this update is enforced. This update, originally named Enable Enhanced Domains, was first made available in Summer ’21.
Where: This change applies to Lightning Experience and Salesforce Classic in Group, Essentials, Professional, Enterprise, Performance, Unlimited, and Developer editions.
When: Salesforce deploys enhanced domains in Spring ’23. You can postpone that automatic deployment via a My Domain option. In Summer ’23, Salesforce deploys enhanced domains in orgs without the feature deployed. You can disable this feature until Salesforce enforces this update in Winter ’24. Orgs created in Summer ’22 or later get enhanced domains by default.
To get the major release upgrade date for your instance, go to Trust Status, search for your instance, and click the maintenance tab.
How: Before you update production, we recommend testing all My Domain changes in a sandbox. A message on the My Domain Setup page indicates whether enhanced domains are scheduled to be automatically deployed in Spring ’23. In that case, admins also see a reminder to enable this feature.
To complete this update, from Setup, in the Quick Find box, enter Release Updates, and then select Release Updates. For Deploy Enhanced Domains, follow the testing and activation steps.
To postpone the automatic deployment of enhanced domains until Summer ’23, disable a My Domain setting before the org gets Spring ’23. In the Routing section of the My Domain Setup page, click Edit, then deselect Automatically deploy enhanced domains with Spring ’23, and save your changes. Repeat this step in each org where you want to postpone the deployment.
