For browsers that block third-party cookies, additional implementation steps are required to ensure Single Sign-On (SSO) functions properly:
* B: SettingstorageDomainOverridefor the group parent site in Global Configuration ensures that all sites in the SSO group share the same domain for storing authentication data, bypassing third-party cookie restrictions.
* C: Configuring a CNAME allows you to use a custom domain for your SAP Customer Data Cloud site, which helps avoid issues with third-party cookies by aligning the domain with your organization's domain.
The other options are incorrect:
* A: CallinginitSSOin theonLoginhandler is unnecessary because SSO initialization is typically handled during the login process itself.
* D: ThecontinueSSOparameter does not exist in SAP Customer Data Cloud's Global Configuration.
