I assume they mean that you can use the Microsoft Authenticator as a second factor for logging into Windows, Android and iOS - not necessarily that it runs on all these systems. Question 265/287 are similar. Q265 lists FIDO2 as well. My theory is that Q265 is older than Q287 and FIDO2 wasn't supported on Android/iOS then. https://learn.microsoft.com/en-us/entra/identity/authentication/concept-authentication-passwordless#microsoft-authenticator Users can sign in to any platform or browser by getting a notification to their phone https://learn.microsoft.com/en-us/entra/identity/authentication/howto-authentication-passwordless-phone This authentication technology can be used on any device platform, including mobile.

Passwordless authentication allows you to replace authentication using a password with authentication requiring “something you have” and “something you know.” An example might be a biometric, such as your face or fingerprint, combined with a code generated by an authenticator device.
