Microsoft 365 Administrator — Question 165

You have a Microsoft 365 subscription.

You need to implement a passwordless authentication solution that supports the following device types:

• Windows
• Android
• iOS

The solution must use the same authentication method for all devices.

Which authentication method should you use?

Answer options

• A. the Microsoft Authentication app
• B. Voice call
• C. multi-factor authentication (MFA)
• D. Windows Hello for Business

Correct answer: A

Explanation

The Microsoft Authentication app is the correct choice as it provides a passwordless solution that works across Windows, Android, and iOS devices using the same method. Voice call and multi-factor authentication (MFA) involve additional steps that do not provide a uniform passwordless experience, while Windows Hello for Business is primarily designed for Windows devices and does not support Android or iOS in the same manner.
