Before there were computers there was security. One of the most important factors that have been used for identity authentication is a password. The authors have many fields that are very dependent on password use such as online financial services and system access such as user account and email access. Password disclosure is a security problem. It is always recommended that a password should be secure enough to prevent attacks; a password should have high entropy and a user must be persuaded to select a password that is difficult to compromise.
