Which feature is essential for ensuring identity verification in sensitive customer transactions?

The key feature for ensuring identity verification in sensitive customer transactions is Two-Factor Authentication. This security measure requires users to provide two forms of identification before they can access an account or complete a transaction. It typically combines something the user knows (such as a password) with something the user has (like a mobile device for a verification code), significantly enhancing security.

In sensitive customer interactions, where data integrity and confidentiality are paramount, Two-Factor Authentication reduces the risk of unauthorized access. It ensures that even if a password is compromised, an additional layer of security is still in place to protect the account.

While other features such as Customer Verification Topics, Account Security Measures, and Privacy Compliance Protocols may play roles in the broader framework of security, they do not specifically address the immediate need for verifying user identity during transactions in the same direct manner as Two-Factor Authentication does.
