Two-Factor Authentication (2FA) and Multi-Factor Authentication (MFA) MCQs

The primary purpose of 2FA and MFA is to enhance user account security by requiring multiple forms of identification.

2FA enhances account security by adding an additional layer of security, requiring a second form of verification.

A one-time passcode sent to a mobile device is an example of a second factor often used in 2FA.

The primary benefit of MFA over 2FA is the addition of more layers of security beyond two factors.

MFA contributes to user account security by requiring multiple forms of identification, making unauthorized access more challenging.

The "something you know, something you have, and something you are" principle in MFA ensures a diverse set of factors, increasing security.

A one-time passcode sent to a mobile device is an example of the "something you have" factor in MFA.

Biometric Authentication contributes to MFA by adding a unique factor based on physiological or behavioral characteristics.

2FA is considered more secure than using only a password because it adds an extra layer of security, requiring an additional verification factor.

TOTP enhances MFA by generating dynamic passcodes that change at regular intervals, adding a time-sensitive factor.

The potential risk of relying solely on passwords is vulnerability to password-related attacks, such as brute force or password guessing.

SMS-based 2FA works by sending a one-time passcode to the user's mobile device via SMS.

In MFA, having factors from different categories ensures a diverse set of factors, increasing security.

PKI enhances the security of MFA by offering secure methods for managing and validating digital identities, often involving the use of digital certificates.

2FA protects against unauthorized access even if passwords are compromised by requiring a second factor, such as a one-time passcode.

The potential risk of using only biometric authentication without additional factors is vulnerability to biometric data theft or spoofing.

Device-based 2FA contributes to user account security by adding a second factor based on the user's device, such as a registered smartphone.

The primary goal of 2FA with SSO is to provide enhanced security while maintaining a convenient single sign-on experience.

OTP Authentication enhances user account security in MFA by generating dynamic passcodes that are valid for a single use or a short time period.

Users should carefully choose the second factor in 2FA or MFA to ensure it is something only they possess and is not easily compromised.

Geo-location-based 2FA contributes to user account security by adding a location-based factor, such as verifying the user's geographical location.

The potential risk of using easily guessable security questions in MFA is vulnerability to unauthorized access through knowledge of personal information.

Organizations can encourage users to adopt 2FA and MFA by educating them on the benefits and importance of using additional authentication factors.

MFA helps prevent unauthorized access due to compromised credentials by requiring additional verification factors, even if credentials are compromised.

Biometric Authentication adds a unique and personal factor in MFA based on physiological or behavioral characteristics.

Hardware Token-based 2FA enhances user account security by generating dynamic passcodes that are stored on the hardware token.

Organizations strive to strike a balance between security and user experience. Implementing user-friendly 2FA and MFA methods ensures that security measures are effective without causing frustration or hindering the user experience.

Adaptive Authentication in MFA dynamically adjusts authentication requirements based on user behavior and risk levels.

Organizations can mitigate the risk of phishing attacks targeting MFA by educating users on recognizing phishing attempts and verifying authentication requests.

2FA offers an additional layer of protection for online transactions by requiring a second factor, enhancing security.
