Question

I use the some WinForm client sample from Problems when migrating from Facebook SDK v5.4 to alpha v6

to see how I can login into Facebook.

My question: Is it possible to login into Facebook without ANY dialog?

 private void btnLogin_Click(object sender, EventArgs e)
        {
            // open the Facebook Login Dialog and ask for user permissions.
            var fbLoginDlg = new FacebookLoginDialog(AppId, ExtendedPermissions);
            fbLoginDlg.ShowDialog();

            // The user has taken action, either allowed/denied or cancelled the authorization,
            // which can be known by looking at the dialogs FacebookOAuthResult property.
            // Depending on the result take appropriate actions.
            TakeLoggedInAction(fbLoginDlg.FacebookOAuthResult);
        }

Answer 1

you are not allowed to store user login/password in the database and use it for “automatic” login – as per Facebook policy:

I. Features and Functionality

…

3 – You must not include functionality that proxies, requests or collects Facebook usernames or passwords.

therefore the answer is – NO, you cannot do that, and you are not allowed to do that.
