OpenID vs LiveID

Written by Alcides Fonseca at 2007/09/23

Microsoft has been using their Passport, now Windows Live ID since Hotmail become popular, and a lot (and when I say a lot, I mean A LOT!) of Internet users do use it.

Recently, Microsoft has released the Windows Live ID Client/Web Authentication SDK that allows users to base their authentication systems on Windows Live ID. This is a great solution for a single sign-on, but all the authentication is relied to Microsoft. Most users won’t find this a problem, but other will.

Well, there is a more open solution to this problem: OpenID. I’ve wrote about this before but now, I have an idea for a new project and I wanted to hear some feedback.

I know that Microsoft has been working together with OpenID to improve the system and make both systems compatible, but I can imagine a quick way of making live ID work as an OpenID: I’m thinking of making my own OpenID provider that uses Windows Live ID as a authentication. Yeah, it will re-delegate the authentication, and probably will take more time, but it will use the authentication you already have (thinking about liveID users).

I wonder if you have any suggestions, or are interested in helping out :)
