Which functionality is NOT part of the My Settings area?

The My Settings area in Salesforce Marketing Cloud is designed to offer users a personal interface to customize their experience and manage specific aspects of their account. This area includes functionalities that help tailor account settings, such as adjusting the time zone to ensure that reports and communications are accurately aligned with local time, or editing display names to personalize the account profile.

Changing an organization's user role is generally a function reserved for administrative purposes and would not be part of individual user settings since it has broader implications for access and permissions across the system.

Managing API keys, while essential for integrations and app connectivity, falls outside the scope of user personalization settings in My Settings. This function typically requires administrative privileges and is handled in specialized areas of the platform dedicated to integration and security configurations rather than individual user preferences.

Thus, the correct answer reflects that managing API Keys is not a functionality available in the My Settings area.
