Microsoft SC-300: Which MFA authentication method can users use from remote location?

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 laptop 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. voice
B. an app password
C. security questions
D. a verification code from the Microsoft Authenticator app

Answer

D. a verification code from the Microsoft Authenticator app

Explanation

The correct answer is D. a verification code from the Microsoft Authenticator app.

The Microsoft Authenticator app is a free app that can be used to generate verification codes for multi-factor authentication (MFA). The app is available for iOS, Android, and Windows devices.

To use the Microsoft Authenticator app for MFA, users must first install the app on their device. Once the app is installed, users must create an account and add their Microsoft 365 account.

When a user attempts to sign in to their Microsoft 365 account, they will be prompted to enter their username and password. After entering their username and password, users will be prompted to enter a verification code from the Microsoft Authenticator app.

The Microsoft Authenticator app will generate a new verification code every 30 seconds. Users must enter the verification code from the app within 10 minutes of receiving it.

The Microsoft Authenticator app is a secure and convenient way to authenticate users for MFA. The app is easy to use and it is available for all major mobile platforms.

The other options are not recommended because they are not as secure or convenient as the Microsoft Authenticator app. Option A, voice, is not a secure option because it can be easily intercepted by someone listening in on the conversation. Option B, an app password, is not as convenient as the Microsoft Authenticator app because users must remember a separate password for each app or service that requires MFA. Option C, security questions, are not as secure as the Microsoft Authenticator app because they can be easily guessed by someone who knows the user well.
