Library usage for only authentication

[Sanjay Patel]

Hallo,
I would like to use socialauth for ONLY AUTHENTICATING USER for facebook,twitter,google in our app.
(i want only username,email,name if disclosed by provider)

Is it possible to set the scope for oauth provider to limited data access like basic profile, email,...etc, as
i would not like to ask user to give us permission for posting or else.

How can i achieve this ?

One of developer saying that by default library asks for permission for sharing for facebook, which i don't want.

Thanks
Sanjay
