Trevin Chow and his team launch their official Windows Live ID blog on MSN Spaces today. He describes what Windows Live ID and how it will affect current Passport users:

Windows Live ID is the upgrade/replacement for the Microsoft Passport service and is the identity and authentication gateway service for cross-device access to Microsoft online services, such as Windows Live, MSN, Office Live and Xbox Live. Is this the authentication service for the world? No 🙂 It's primarily designed for use with Microsoft online services and by Microsoft-affiliated close partners who integrate with Windows Live services to offer combined innovations to our mutual customers. We will continue to support the Passport user base of 300+ Million accounts and seamlessly upgrade these accounts to Windows Live IDs. Partners who have already implemented Passport are already compatible with Windows Live ID.

Head on over and subscribe to the Windows Live ID Blog! Keep your eyes on this blog for more information on Windows Live ID in the days ahead!
