- A
Passwordless authentication using Microsoft Authenticator
Microsoft Authenticator app can be configured for passwordless phone sign-in, enabling users to authenticate with a biometric gesture or PIN without entering a password.
- B
Microsoft Entra Connect Sync Health
Why wrong: Microsoft Entra Connect Sync Health monitors and provides insights for hybrid identity infrastructure (e.g., AD FS, sync). It does not enable passwordless sign-in with biometrics.
- C
Microsoft Entra ID Protection
Why wrong: Microsoft Entra ID Protection helps detect and respond to identity-based risks and compromised credentials. It does not provide a passwordless authentication method.
- D
Self-Service Password Reset (SSPR)
Why wrong: SSPR allows users to reset their own passwords using various methods (e.g., phone call, email) but does not provide biometric-based sign-in.

This SC-900 practice question tests your understanding of describe the capabilities of microsoft entra. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 uses Microsoft Entra ID (Microsoft Entra ID) and wants to allow users to sign in using biometrics (fingerprint or face) on their mobile devices instead of passwords. They want this to work for both iOS and Android devices. Which Microsoft Entra ID feature should they enable?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Passwordless authentication using Microsoft Authenticator
Option A is correct because Microsoft Authenticator supports passwordless authentication using FIDO2-based biometric verification on mobile devices. This feature allows users to sign in with a fingerprint or face on both iOS and Android, eliminating the need for a password while leveraging the device's built-in biometric capabilities.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse Self-Service Password Reset (SSPR) with passwordless authentication, but SSPR only resets passwords and does not enable biometric sign-in without a password.
Detailed technical explanation
How to think about this question
Passwordless authentication with Microsoft Authenticator uses FIDO2/WebAuthn standards, where the private key is stored in the device's Trusted Platform Module (TPM) or secure enclave, and biometric verification unlocks the key. This approach provides phishing-resistant authentication because the credential is bound to the device and cannot be intercepted or replayed. In a real-world scenario, organizations can enforce a conditional access policy to require passwordless sign-in for mobile users, reducing password-related attacks.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
