No other way except to approch a professional which is illegal as it is not so important to do so.
It`s not possible to do so for a
you will require an expert or a computer hacker for it who s expert in doing so,
but he will charge you a lot and if someone finds out that you have done it then it may land in soup also as it is illegal to do so.
Be careful in doing so.
You will also require software for it if you want to figure out face book passwords.
The advice is not to do it and don`t let yourself fall into any trouble.
I hope you have changed your mind by now.
