Quick Answer
The answer is FIDO2 security key. This is the correct phishing-resistant authentication method for Microsoft Entra ID because it relies on public key cryptography, where the private key never leaves the device and cannot be intercepted or replayed by an attacker. Unlike SMS codes, which can be intercepted via SIM swapping, or push notifications, which can be bypassed through MFA fatigue attacks, FIDO2 uses a hardware-bound key that cryptographically signs authentication requests, making it immune to phishing. On the MS-102 exam, this question tests your understanding of modern authentication standards under the “Manage authentication” domain; a common trap is confusing Temporary Access Pass (TAP) as a primary method when it is only for onboarding or recovery. Remember: FIDO2 is the only option that is both passwordless and phishing-resistant by design. Memory tip: think “FIDO2 fights phishing with a physical key.”
This MS-102 practice question tests your understanding of implement and manage microsoft entra identity and access. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Your organization requires that all administrators use phishing-resistant authentication methods. Which Microsoft Entra ID authentication method meets this requirement?
SMS-based verification
Why wrong: SMS can be intercepted or phished.
Microsoft Authenticator push notification
Why wrong: Push notifications can be subjected to MFA fatigue attacks.
Temporary Access Pass
Why wrong: TAP is a time-limited password, not phishing-resistant.
FIDO2 security key
FIDO2 is phishing-resistant by design.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
FIDO2 security key
FIDO2 security keys are phishing-resistant because they use public key cryptography and cannot be phished. Option A is wrong because SMS is vulnerable to phishing. Option B is wrong because push notifications can be phished. Option D is wrong because a temporary access pass is not a primary authentication method.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
