ok, i am developing a game, and i am trying to figure out a way on how to minimize multiplaying, or players having more than 1 account.

does anyone have any good ideas on how to do this?

make the first account they log in to on that ip the primary account for the ip for a couple of hours and then make them answer extremely guessable security questions to log in to a secondary account

or you could keep the last account logged into and the time+date in a cookie and then check that

If it's free, you cant really do much to prevent people from operating two different accounts...

If I want to, I'll use a different ip address, different username(duh)/password(duh) and different email, different browser, etc...

The only way you could prevent it would be to charge... and even then if i wanted to I'd just use a different credit card (though you probably wouldnt complain ;))

There's nothing you can do, realistically.

IP information can't be used because many people can legitimately change IP addresses between requests.

You could send the credentials as postal letter
or make a valid and assured thawte or CAcert certificate mandatory
or ...

I'm just putting this out there, but what about cookies? Sure, you can edit them, but not your everyday average joe knows how to.
