Answer 1

You actually don't need to pass or call auth_type:rerequest. This is already done by facebook. If you check FBSDKLoginManager, the code does it for you.

-(NSDictionary *)logInParametersWithPermissions:(NSSet *)permissions
{
    if ([FBSDKAccessToken currentAccessToken]) 
       {
             loginParams[@"auth_type"] = @"rerequest";
       }
}
