One username and password for all the sites that you use! Wait doesn’t Microsoft do that with Passport? Yeah, but what if you don’t trust Microsoft?
Hummm…. Well, what do you think about this scheme: You can choose any authentication provider be it a very establish, trusted company like Verisign or a niche player like www.MyOpenId.com. And any site that implements the OpenID protocol can use that ID.
This is something I have been wanting to see for a long time. Check it out at www.OpenId.net. Also, there is a wordpress plugin verselogic.net/projects
So, expect to see all my sites OpenID enabled soon.
