Question
You have a Microsoft 365 subscription that uses Microsoft Intune Suite. You use Microsoft Intune to manage Windows 11 devices. You need to implement passwordless authentication that requires users to use number matching. Which authentication method should you use?
Options
- AMicrosoft Authenticator
- Bvoice calls
- CFIDO2 security keys
- Dtext messages
Explanation
Microsoft Authenticator is the correct answer. It is the only listed method that supports passwordless authentication with number matching. Number matching is a specific security feature where during sign-in, the user is shown a two-digit number on the login screen and must select the matching number in the Authenticator app - this prevents MFA fatigue attacks. FIDO2 security keys (C) are passwordless but use physical key presence, not number matching. Voice calls (B) and text messages (D) are OTP-based legacy MFA methods that do not support passwordless flows or number matching.
