How does multi-factor authentication enhance cloud security?

Multi-factor authentication (MFA) enhances cloud security by requiring users to verify their identity through multiple factors, typically including something they know (like a password), something they have (like a smartphone for receiving a verification code), and something they are (like a fingerprint or facial recognition). This approach adds layers of security beyond just a password, making it more difficult for unauthorized users to gain access. While MFA significantly increases security, it is not foolproof and should be used in conjunction with other security measures such as encryption, regular audits, monitoring, and access controls to provide a more comprehensive security posture.
