Most interesting about Microsoft Passport is that it fully supports the Fast IDentity Online (FIDO) users of cloud services supporting FIDO is that there will no longer be passwords associated with the user’s account. respond to the IDP. Another key point to the Microsoft Passport credential system is that the user needs to enroll every device used to access the service (IDP).
