Cloud Gateway Fundamentals Email Security Practice Test

Multi-factor authentication enhances email security by requiring multiple forms of verification before granting access to emails. This process significantly adds layers of protection, making it much more difficult for unauthorized individuals to gain access to an account. For example, even if a malicious actor manages to obtain a user's password, they would still need to provide a second form of verification, such as a code sent to the user’s mobile device or a biometric check. This requirement effectively reduces the chances of unauthorized access, as obtaining both factors of authentication is much harder than simply cracking a password.

In contrast, options that suggest simplifying the login process or providing a single layer of security do not contribute to enhanced security. The essence of multi-factor authentication is its complexity, which is what makes it a strong defense mechanism against various types of cyber threats.
