By the end of last year, two big players in the software and internet business have made some interesting steps forward in supporting OpenID.
Yahoo! Is Testing Simple Registration
In November Yahoo! started testing the Simple Registration extension (Sreg) with a limited number of Relying Parties. This extension allows sharing of some basic profile information stored at the OpenID Provider.
As far as I know, the tests are not finished yet, though users can already preview the implementation. As you can see from the screenshot below, I used my Yahoo! OpenID to log in to Plaxo. Don’t mind it’s all German, though.
My real name, nickname, email address (I crossed it out), language, and timezone are forwarded to Plaxo. As usual, Yahoo! provides some informative explanations to users, so they are always informed what’s happening. That’s a real advantage of Yahoo!’s entire OpenID implementation.
Microsoft Live ID Is an OpenID
Another news that almost got unnoticed by me, in October Microsoft announced that Live IDs will be OpenIDs. Microsoft will support the OpenID 2.0 standard only.
Currently, you have to create a Live ID test account to see it work. Already established Live IDs don’t work with the demo. So hopefully, the Microsofft’s tests will end soon. I hate creating test accounts. 
Sorry Carsten, but the LiveID is definitly not more than a test. Yes, you can create an account, but thats all. Besides them it is not worth to talk about it, isn’t it. Its ok to provide some testsides, but there is nowhere an explanation or some other help for the user. If i clicked the support-button, i got an authorization-error. this side confuses me, is buggie and definitly betagammadelta and if you ask me, the openid-guys have to wait to write about it till it works;)
Yes, it is only a test currently. So maybe you’re right, and I shouldn’t have posted it. Especially, on a blog like this one. Well, I have to consider that for forthcoming posts.
Sorry, but why is OpenId does not work!
What do you mean? Can’t you comment with your OpenID here? I just tried it and it works.
This intergration is a msut have as everyone needs to use windows live ID if it doesn’t support windows live then we will still always have multiple ID’s for websites guys
but good work!
