In QuestionPro, users are allowed to manage and update their own personal details—such as name, phone number, and email address—for their individual accounts. This behavior is by design, and currently, admins, super admins, or other users cannot restrict or control a subaccount’s ability to change their own email address or other personal details.

As a workaround, you may use SSO (Single Sign-On) to ensure users can access QuestionPro only through their organization’s login credentials, helping maintain controlled and authenticated access.
