Spring Social Authentication

[Laedislaw]

Hello,

I'm trying to understand how Facebook Signin procedure works.

If I understand correctly, the authenitcation procedure involves going through. 1) facebook authenitcation, then 2) local application. authentication

For example. I click on "signin with facebook" button situated in my app, I am taken to faacebook where I enter my credentials (if successful) I am redirected back to my app's signnin page where I enter username/ password for Spring Security, only then I am signed in.

The above process is a bit too long. I need a solution that involves only one authentication step e.g. Username/Password used only once, if successful they are authnticated on both sites. Can I do this with Spring Social?

Thanks
