I'm an O365 admin with several tenants/organizations, so to be able to use password-less authentication would make life so much easier.
But right now:
"One of the prerequisites to create this new, strong credential, is that the device where it resides is registered within the Azure AD tenant, to an individual user. Due to device registration restrictions, a device can only be registered in a single tenant. This limit means that only one work or school account in the Microsoft Authenticator app can be enabled for phone sign-in."
This phone sign-in option went live for public preview in September 2018, so not that long ago. But there must be lots of people out there like me that wish to use the password-less option by phone sign-in for multiple tenants.
