Microsoft is broadening the scope of Windows Live ID. Already it is used to view licensing keys and store OneNote data, as well as provide 5GB of free storage. Starting with Windows 8, the Live ID logon now will be a password and forms manager as well.
Because it is integrating the capabilities into the operating system, Microsoft can add features that standalone password managers cannot. For instance, with Windows 8 Microsoft is throwing in a lightweight environment manager that can save a wide range of settings such as your lock screen picture, desktop background, user tiles, and browser favorites and history, among many others. They automatically sync when you log into Live ID. Will this conflict with third-party environment managers such as Quest or AppSense? Windows 8 ships in October so we'll find out soon.
Additionally, Microsoft also lets you log into Outlook.com, Windows Messenger, and (formally known as) Metro apps without a password interface, and the setting and last-used state persist across all your Windows 8 PCs.
