Google Friend Connect - only using Google, not others (e.g. Yahoo or Twitter)

I'm using Google Friend Connect for开发者_运维知识库 user authentication.

By default, when you use this, Google lets you use "Google", "Twitter", "Yahoo" and a few others like "AOL" and "OpenID".

Is there an easy way to actually choose which service I want to use? For example, I only want to use Google account for this. What is the best way to filter other services out?

If you want to use only Google account into your site than you can use OpenID.

Here is the step-by-step process to implement OpenID on your ASP.NET application using DotNetOpenOAuth libraray (URL: https://www.google.com/accounts/o8/id – this is the unique OpenID URL of Google Account).

Tutorial describes how to implement Google login( yahoo,etc only just change the URLs, source code is same) in PHP.
