So there it goes - Linux is a secure OS. No, really it is. Despite the title of this post, Linux is actually a secure system. Before we proceed to the main topic, let us consider a few points:

Linux is flexible to a very large extent.
Linux's administrator account is called 'root'.
Linux systems never deny access to any resource whatsoever to the root account. If there are any restrictions in place, the root can remove those as well.
The root account can set and change the password of any user.
To change the password of root, you need to first login as root!
It is the 5th point where the problem is. Much like in Windows, you would get locked out of the system. But since Linux is not (as pathetic as) Windows, there are ways to work around it. Let us see some of them.

If you face any problem using this trick, you can write a comment and I will do my best to help you.
