A company's IT department needs to enhance the security of its corporate email accounts. They decide to implement a process that requires users to authenticate through their password and an additional method, such as a code sent to their phone. What security measure should the IT department implement?
Two-factor authentication (2FA) adds an extra layer of security by requiring a second form of identification in addition to a password. This can include a code sent to a mobile device, a fingerprint scan, or another method. 2FA significantly enhances security as it requires two distinct forms of verification, making unauthorized access difficult.
