Welcome to the Microsoft® .NET Passport Software Development Kit (SDK).

.NET Passport is a core component of the Microsoft .NET initiative and the foundation of the upcoming Microsoft .NET My Services. Microsoft .NET provides the platform for the next-generation Internet. To reach the next level of online business, your company needs a consistent way to refer to individuals, groups, and companies online; a way to notify them of important events; and a schema for storing essential global data to orchestrate applications, Web services, and devices on behalf of users, with their full control and consent.
