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?
To implement a passwordless authentication solution that works across Windows, Android, and iOS devices, the Microsoft Authentication app is the best choice. This app supports passwordless sign-ins and is designed to work across a variety of device types, offering a consistent authentication method. Voice calls and multi-factor authentication are not specifically passwordless and do not fulfill the requirement for the same method on all device types. Windows Hello for Business is limited to Windows devices.
Wrong answer. A is the correct answer (Microsoft authentication app)
Microsoft authentication app is not supported for Windows?
