What does MFA stand for in cloud security?

MFA stands for Multi-Factor Authentication, which is a security measure that requires users to provide two or more verification factors to access their accounts or systems. This approach enhances security by combining something the user knows (like a password), something the user has (like a smartphone or hardware token), and sometimes something the user is (like biometric verification).

The use of MFA is critical in cloud security due to the increasing threats posed by cyber attacks, which can exploit weaknesses in single-factor authentication. By implementing MFA, organizations significantly reduce the risk of unauthorized access to sensitive data and resources, as gaining access would require multiple credentials that are more difficult to compromise simultaneously.

The other options do not accurately represent the concept of MFA. For instance, multiple feedback authentication and multiple-factor access do not align with the recognized terminology or methodology used in cybersecurity practices, and multi-feedback access does not connote a factor-based verification system. Thus, Multi-Factor Authentication is the established and correct term in this context.
