The answer is to set the IAM password expiration period to 0, which forces an immediate password change for existing users on their next login. This works because a password expiration value of 0 days effectively marks all current passwords as expired, overriding the fact that the new policy itself does not retroactively invalidate existing credentials. On the AWS Certified Security Specialty SCS-C02 exam, this scenario tests your understanding that setting a password policy only governs future password creation; it does not force existing users to comply. A common trap is assuming the policy alone enforces compliance, or that manually resetting each user’s password is required—neither is correct. The key memory tip is “expire to enforce”: if you need to force change, set the expiration to zero, not just the policy rules.
SCS-C02 Management and Security Governance Practice Question
This SCS-C02 practice question tests your understanding of management and security governance. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company has a requirement that all IAM users must use strong passwords. The security engineer needs to enforce a password policy that requires minimum 12 characters, at least one uppercase letter, and at least one number. The engineer sets the password policy in IAM. However, existing users with weak passwords are not forced to change them. What should the engineer do to enforce the policy for existing users?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "least"
Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set the password expiration period to 0 to force immediate password change.
Option D is correct because setting the password policy to expire existing passwords will force users to change them on next login. Option A is wrong because the policy is already set; users are not forced to change. Option B is wrong because allowing users to change passwords does not enforce the policy. Option C is wrong because resetting passwords manually is not scalable and not required.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Manually reset each user's password to a strong password.
Why it's wrong here
This is not scalable and users could change it back.
✗
Enable 'Allow users to change their own password' in the policy.
Why it's wrong here
This allows but does not force password change.
✗
Re-apply the password policy to each user.
Why it's wrong here
The policy is already applied; users are not forced to change.
✓
Set the password expiration period to 0 to force immediate password change.
Why this is correct
Setting expiration to 0 forces users to change passwords on next login.

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
