Openid: Looks good.

I only saw this thing today, which is very good for solving the SSO problem.

This article makes it very clear that: http://www.zuola.com/weblog? P = 506

I will briefly introduce how openid works:

1. You must have a website a. No matter how long or short your website URL is, you only need to be able to be accessed. You can register this website on the openid server, fill in your personal data. You can even fill in personal data of different levels for different purposes. Each time you choose to use personal data or do not need it, this openid server can be created by yourself or a trusted openid server. For example, your url is your passport, and the openid server is the location of your account.
2. You can embed code similar to the following on the page of website:
   <LINK rel = "openid. Server" href = "http://pip.verisignlabs.com/server"/>
   <LINK rel = "openid. Delegate" href = "http://zola.pip.verisignlabs.com"/>
3. When you use the URL of your website A as the ID to Register website B that supports openid, website B will visit website a and find the above Code from the HTML code of the page, website B will access the openid server http://pip.verisignlabs.com/server, and we will use http:/// C. At this time, you can choose to allow B to use some of your personal data, so it is very convenient to complete the registration process.

================================================================ ========================

In fact, you do not need a website. You can find an openid provider to pull it.

For example, register an openid, yuandafeng,

He gave me a URL: http://yuandafeng.myopenid.com/

Accessing this page will prompt you that this is an identity page for http://yuandafeng.myopenid.com/

Find a website that supports openid

Example: www.yupoo.com/

Enter yuandafeng.myopenid.com to log on to myopenid.com /.Www.yupoo.com/You can log on to your website.

However, the promotion is a technology-independent issue...
