How does Stack Overflow allow new users to login into Stack Overflow using their Gmail or Facebook or Yahoo accounts? I am working on a little project website and I was curious how Stack Overflow does this. Do I need to get permission from these companies to do this or can I just do it?

推荐答案

StackOverflow(和所有其他 StackExchange 站点)使用 OpenID.

StackOverflow (and all other StackExchange sites) use OpenID.

OpenID 是一种分散式身份验证协议，可让人们轻松注册和访问网络帐户.

OpenID is a decentralized authentication protocol that makes it easy for people to sign up and access web accounts.

Yahoo、Google 和 facebook 都是 OpenID 提供商，因此只需在您的网站上实施它就足以让您的用户能够使用它们(以及任何其他 OpenID 提供商)登录.

Yahoo, Google and facebook are all OpenID providers, so simply implementing it on your site will be enough for your users to be able to login using them (and any other OpenID provider).

无需获得许可 - 许可将由您的应用程序的用户获得.

There is no need to get permission - the permission will be gotten by the users of your application.
