Which feature aims to protect NSM accounts from unauthorized access?

The feature designed to protect NSM accounts from unauthorized access is two-factor authentication. This security measure adds an additional layer of protection by requiring not only a username and password but also a second form of verification, such as a code sent to a mobile device or a biometric check.

This process significantly reduces the risk of unauthorized access because even if a malicious actor obtains a user’s password, they will still need the second authentication factor to gain access to the account. As a result, implementing two-factor authentication is an essential practice for enhancing account security and ensuring that only authorized users can access sensitive information.

While options such as account lockout, session timeout, and IP whitelisting can contribute to account security, they do not specifically address the need for multifactor authentication, which is key in preventing unauthorized access at the account level.
