I have a few nagging computer user accounts that regularly ask me to change password. Some of them even remember history of about ten old passwords to prevent me from using them again.
As a side effect, I have to think of new passwords again and again. Later, I use random password generators that are freely available on the Internet. Just for fun, I have also developed a random password generator of my own and you can see it at the following link.
