Which of the following practices is beneficial for improving customer verification?

Requiring two-factor authentication (2FA) is a widely recognized and effective practice for enhancing customer verification. This method adds an extra layer of security beyond just a username and password. When a user attempts to log in, they must not only provide their password but also verify their identity through a second factor, typically a temporary code sent to their mobile device or generated by an authentication app. This significantly reduces the risk of unauthorized access, as even if someone has managed to acquire a user's password, they would still need the second factor to complete the login process.

Implementing 2FA can help protect sensitive information and accounts from breaches caused by phishing attacks or stolen credentials. As such, it fosters greater trust between users and the platform. This practice is particularly valuable in environments dealing with sensitive financial information, reinforcing security protocols and promoting a safer overall user experience.
