A county CIO asks how single sign-on (SSO) differs from multifactor authentication (MFA) for city apps. Which comparison is accurate?
Select an answer to reveal the explanation.
Short Explanation
SSO is the "one badge for many buildings" convenience story. MFA is the "badge plus PIN" strength story. They solve different problems and often work together, not as clones of each other.
Full Explanation
Single sign-on lets users authenticate once and reach multiple applications with that identity session, reducing password fatigue. Multifactor authentication adds additional verification factors to raise assurance at sign-in. Comparing them correctly at fundamentals depth means recognizing convenience versus stronger authentication—not treating them as the same control or as firewall/storage settings.
