The growth of technology in the field of computer science & the popularity of information technology has changed the means of information exchange from letters to electronic messages. Security became a major concern with the advent of electronic messages as it led to higher possibilities of information attacks. One of the proposed solutions to this problem is the usage of passwords to protect the information. Password is a string of characters used for user authentication to prove identity or approval to gain access to a resource, which should be unknown to or kept secretive from unauthorized users.
