Which of the following is a primary benefit of using multi-factor authentication in cloud services?

Using multi-factor authentication (MFA) in cloud services significantly enhances security against unauthorized access. This method requires users to provide multiple forms of verification before they can gain access to their accounts. Typically, this involves something they know (such as a password) combined with something they have (like a smartphone app or hardware token) and sometimes something they are (biometric verification, like a fingerprint).

This layered approach is crucial in protecting sensitive information because even if an attacker were to obtain a user’s password, they would still need the additional authentication element to gain access. MFA greatly reduces the likelihood of unauthorized access and protects against common threats such as phishing attacks and credential stuffing.

While options like increased user convenience, faster login procedures, and reduced password complexity may seem appealing, they do not accurately represent the primary purpose of implementing multi-factor authentication. The primary aim of MFA is to bolster security, making option B the most appropriate choice.
