Once it has been set, it remains associated with the account and is available as part of the account-security information. However, it can be modified if the current question or answer is no longer suitable.
Updating the security question can be helpful if the answer has become difficult to remember, has been shared with someone else, or no longer provides an appropriate level of privacy. When choosing a new question and answer, use information that is memorable to you but not easy for others to guess. Avoid using details that may be publicly visible on social media.
Before confirming the change, check the new answer carefully and keep it confidential. If you cannot complete the modification or have questions about your account, contact vivo customer service for further assistance.
