+Available in Windows 10, version 1803. Specifies the list of domains that are allowed to be navigated to in AAD PIN reset and Web Sign-in Windows device scenarios where authentication is handled by AD FS or a third-party federated identity provider. Note this policy is required in federated environments as a mitigation to the vulnerability described in [CVE-2021-27092](https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-27092).
+
+**Example**: If your organization's PIN reset or Web Sign-in authentication flow is expected to navigate to two domains, accounts.contoso.com and signin.contoso.com, the policy value should be "accounts.contoso.com;signin.contoso.com".
