CAS-004 Practice Question: A company's internal audit found that employees…
A company's internal audit found that employees often share passwords. Which policy change would BEST address this?
⚠ Common exam trap
CompTIA often tests the distinction between administrative controls (training, policies) and technical controls (MFA), where candidates mistakenly choose training (Option D) because it directly addresses the behavior, but the question asks for the BEST policy change to address the risk, which requires a technical enforcement mechanism like MFA.

Correct answer & explanation
✓
Implement multi-factor authentication
Multi-factor authentication (MFA) directly mitigates the risk of password sharing by requiring a second authentication factor (e.g., a one-time passcode from a hardware token or authenticator app, or a biometric) in addition to the password. Even if employees share passwords, an attacker cannot authenticate without the second factor, which is typically not shared. This policy change addresses the root cause—unauthorized access via shared credentials—rather than trying to prevent the sharing behavior itself.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Implement multi-factor authentication
Why this is correct
MFA provides an additional layer, making password sharing less effective for unauthorized access.
- ✗
Increase password complexity requirements
Why it's wrong here
Complexity alone does not prevent sharing.
- ✗
Require password changes every 30 days
Why it's wrong here
Frequent changes do not stop password sharing.
- ✗
Provide security awareness training on password sharing
Why it's wrong here
Training may help but is less effective than a technical control like MFA.
