What is Open ID ? How to implement on my own blog post?

I have a website and I wanted to be开发者_C百科come an open ID publisher. How to do that?

Depending on your exact requirements, you might want to try OpenID delegation instead. You can then use your website as a layer of abstraction over a third party provider.

As you're building for asp.net - take a look at DotNetOpenAuth. It's a free, open-source library that can make your asp.net webrite an OpenID provider (your website can be used to identify you) or a relying party (users can log in on your website using OpenID).

In fact, StackOverflow uses it as well, and so do I. It has a number of examples, and it's pretty reliable and secure.. Definitely recommended! :)

If you just want to run your own identity server, then a good place to start looking is here. I run phpMyID on my site that acts as an openID server for me, it was easy to set up, seems to work, and no-one has stolen my identity ..yet.
