Question 20

Explanation

The correct answer: Multi-factor authentication (MFA) requires a user to provide two or more verification factors to gain access to a resource, such as an application, online account, or a VPN. These factors can be something the user knows (like a password), something the user has (like a smart card or mobile device), or something the user is (like a fingerprint or voice). The primary purpose of MFA is to create a layered defense and make it more difficult for an unauthorized person to access a target, hence increasing the security of user accounts. The incorrect answers: While MFA does add an additional step to the login process, its primary purpose isn't to make logins more difficult. Instead, it is designed to provide additional security. Although the process may take a bit longer than single-factor authentication, many users find the added security to be worth the additional time. To provide users with multiple login options is incorrect because MFA doesn't necessarily provide multiple login options. Instead, it requires users to authenticate themselves through multiple methods, each from a different category of credentials. It's not about providing options, but about demanding additional verification to confirm a user's identity. MFA actually makes the login process a bit more complex by requiring multiple forms of verification. Its purpose is not to simplify the login process, but to enhance security by ensuring that users are who they claim to be.
