There are over 500 million Windows Live IDs that are used every month. That is a lot of users who can sign into web sites. In addition to base level authentication you can also pre-fill registration forms with things such as the user’s email address, so that information doesn’t need to be manually typed again and again (remember this video?). Users are able to quickly sign in and sign-up without needing to enter a username and password. Many users will already be signed into Windows Live (e.g. Hotmail) so they won’t need to enter their password again and can effectively sign into your web site in 2 clicks (1 on the in the page, 1 within the popup window).
There are several additional things we’ve been working on from a user experience perspective. We’ll cover these in more detail in subsequent posts but they include:
For more information about the underlying technology of authentication, see this post or this page.
Another thing we’ve heard from customers, and observed on the web, is that customers want to be able to automatically find their friends on a web site or be able to invite them to a site via email. Historically the Windows Live Contact API enabled users to take their entire address book with them to another web site for the purposes of friend finding (indexed by email) and friend inviting (by sending an email), or in very specific circumstances migrating their address book.

Hi angus, i'm trying to access to http://manage.live.com but to access them first i have to register on beta program, i already do that in june but i don't have response about that, please help.
@Marco: Yes, you can use pure JS (except for the OAuth callback, which must be done server-side in .NET, PHP, or whatever you prefer).
@Gerardo: You probably haven't registered for the Beta program. Take a look here for more info: social.msdn.microsoft.com/.../8c31ec14-181b-4f93-ac6d-e63dcab1a0d5
Hi Angus I'm try to register a new application in https://manage.dev.live.com but it always send me back to http://dev.live.com, it might be because the page is offline?? i solve this going to http://live.azure.com here i can register the application.
.NET is not required and a simple JS library would be enough? Sounds too good to be true ^^
@keoz - the email address will still be in the Connected User's profile, just not their friends' email addresses.
Is good you are removing e-mail addresses from users identity, currently I need to retrieve e-mail if the user does not have a name and is annoying because creates moro code paths, but now since every user has a name we only need that :)
