______ is possible today.

• A. Single sign-on
• B. Reduced sign-on
• C. Both A and B
• D. Neither A nor B

Answer: (B)

The idea being tested is how authentication can be made much less burdensome for users with today’s technology. Single sign-on lets you authenticate once to access many applications, which already reduces how often you’re prompted. But modern identity setups go further: with persistent sessions and refresh tokens, your authenticated state can be kept across apps for a period, so you aren’t prompted to sign in again and again. When you add passwordless methods (like hardware keys or biometrics) plus device trust and adaptive controls, you can eliminate repeated sign-in prompts while still enforcing security policies. That combination shows that reduced sign-on is feasible today, which is why this option is considered the best answer.
