Why each option
The Microsoft Authenticator app provides a consistent passwordless authentication method across Windows, Android, and iOS devices.
The Microsoft Authenticator app supports passwordless phone sign-in for accounts across Windows, Android, and iOS devices by sending a notification to the app for user approval, fulfilling the requirement for a single authentication method across all specified platforms.
Voice call is a form of multi-factor authentication (MFA) but requires a password for the initial factor and is not a passwordless solution.
Multi-factor authentication (MFA) is a broader category and not a specific passwordless authentication method itself; it typically involves a password plus an additional factor.
Windows Hello for Business is a passwordless solution, but it is exclusive to Windows devices and does not support Android or iOS.
