Without those methods, single sign-on (SSO) can also stop working. To preserve admin access to Salesforce and prevent end-user frustration, verify your backup authentication methods. In preparation for your My Domain change, determine the post-deployment steps to reestablish authentication for your org, including resetting the affected verification methods for your users. - **[Deploy My Domain Changes](https://help.salesforce.com/s/articleView?id=xcloud.domain_name_testing_and_rollout.htm&release=264.0.0&type=5)** After you change your My Domain and Salesforce provisions those changes, deploy your org’s new My Domain. Only after you deploy your new My Domain can you test your new URLs. And your users can’t use the new My Domain URLs until you deploy the updated My Domain. - **[Update Authentication After a My Domain Change](https://help.salesforce.com/s/articleView?id=xcloud.domain_name_auth_update.htm&release=264.0.0&type=5)** Determine whether your My Domain change requires that you update your authentication settings. Then learn about the authentication settings that can be impacted after a My Domain change and make the required updates. If your My Domain login host name or sites host name changed when you deployed a My Domain change, update your authentication settings. - **[Update Your Org for My Domain Changes](https://help.salesforce.com/s/articleView?id=xcloud.domain_name_guidelines.htm&release=264.0.0&type=5)** When you deploy a change your My Domain, your Salesforce org’s login URL and application URLs change. URLs that are dynamically constructed—for example, URLs generated via the `DomainCreator` Apex class—use the new URLs automatically. However, some Salesforce functionality requires an update to work with your new URLs. Similarly, custom code, your network configuration, and third-party integrations that use the old URLs require updates. To ensure a smooth transition to your new URLs, update references to your old URLs. - **[Test My Domain Changes](https://help.salesforce.com/s/articleView?id=xcloud.domain_name_test.htm&release=264.0.0&type=5)** Follow these guidelines to test My Domain changes and to ensure a smooth transition to the new My Domain URLs.
