Question
You have a Microsoft 365 tenant.
All users have mobile phones and Windows 10 laptops.
The users frequently work from remote locations that do not have Wi-Fi access or mobile phone connectivity. While working from the remote locations, the users connect their laptops to a wired network that has internet access.
You plan to implement multi-factor authentication (MFA).
Which MFA authentication method can the users use from the remote location?
A. a notification through the Microsoft Authenticator app
B. SMS
C. email
D. Windows Hello for Business
Answer
D. Windows Hello for Business
Explanation
In the given scenario, users frequently work from remote locations without access to Wi-Fi or mobile phone connectivity. They connect their Windows 10 laptops to a wired network with internet access. Considering these constraints, the most suitable MFA authentication method is Windows Hello for Business.
Windows Hello for Business is a built-in MFA solution for Windows 10 devices that uses biometric data (such as facial recognition or fingerprint) or a PIN to authenticate users. It does not require a mobile phone or an internet connection to function, making it ideal for users working in remote locations with limited connectivity.
The other options are not suitable for the given scenario:
A. Microsoft Authenticator app notifications require a mobile phone with internet connectivity.
B. SMS-based MFA requires a mobile phone with cellular service.
C. Email-based MFA, while possible, is less secure and not recommended for high-security environments.
Therefore, Windows Hello for Business is the best choice for implementing MFA in this scenario, as it allows users to securely authenticate without relying on Wi-Fi or mobile phone connectivity.
