Sometimes it is needed to recover lost password. So in this type of situation this type of tutorial is needed. I can share my experience about this. I was so busy in my work for one month, so i can’t be able to log in my Linux OS. Generally i remember the password. Also I keep my password writing. But at that time i can’t be able to remember the password. The password i enteres, showing wrong password. I was also unable to find the paper i wrote the password. So then i need to recover lost password.
