Microsoft 365 Administrator — Question 148

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. FIDO2-compliant security keys
• C. multi-factor authentication (MFA)
• D. Windows Hello for Business

Correct answer: A

Explanation

The Microsoft Authentication app is designed for passwordless authentication and works seamlessly across Windows, Android, and iOS devices, making it the correct choice. FIDO2-compliant security keys are not consistent across all device platforms, while multi-factor authentication (MFA) and Windows Hello for Business do not provide a uniform passwordless solution across the specified devices.
