Passport is a unique service offered by Microsoft that allows users to create an identity that they can use to authenticate themselves with any Passport-enabled applications. This allows users the convenience of creating and using one identity across a number of unrelated applications. As a developer, instead of spending valuable development time developing an authentication system and user database, you can use Passport and focus your efforts on your application development.
