什么是OpenID

OpenID是一个分布式的、轻量级的、单一帐户、便于转换的认证方式，它正在当前的互联网内引起震荡。现在有超过8,000网站支持OpenID，这个数字正以每周5%的速度增长。一些大网站，如Google Blogger, AOL, VeriSign, France Telecom 和Sun Microsystems都已经或声明面向1.6亿用户支持OpenID。

这种简单的技术能让你用你的网址作为账户。它是为以简单的方式解决单一帐户登陆问题而设计的。就像使用email地址做账户一样，OpenID使用你拥有的网址(URL)来登录其他网站。同样像使用email地址一样，你可以拥有多个OpenID，用以工作、个人或者任何其它用途。但是与email方式不同的是，除非你允许，否则那些网站不会得到你的个人信息或给你发垃圾邮件。

OpenID是一个网址。一个例子：‘http://bob.myopenid.com/’, 当我想登录启用OpenID的网站时，只需要在登陆框输入‘http://bob.myopenid.com/’。

It was a long time ago when there was a discussion in the wp-hackers list about intergrate OpenID into wordpress. There was suggestion to put it into wordpress core. But there seems to be a final decision from ticket #3616 that it won’t get into core.

That, i think, is partly because of the excellent plugin wp-openid.

Closing as WONTFIX for now. Multiple plugins exist for this functionality. You have also combined the two issues of consuming and serving.

I was waiting for the openid support in wp core until I saw this ticket today. So I installed WP-OpenID right away. It’s a good plugin, though no many option. Support OpenID in commenting is what I wanted for a long time, but I really want to turn off the openid login support – that adds an user in my blog!

Anyway, friends, you can use your openid url to comment on my articles now.
Enjoy!
