                      1] The Password  

Introduction

The password is a phenomenal that has being in existence since the dawn of the web, in fact passphrases were used by ancient societies  as a security measure,and this just goes to show the innovative nature of mankind throughout the ages.The  password is a mechanism that provides a secure gateway  or a loophole  to CyberSecurity ;whichever way you look at it as there are two sides to a coin( others say 3 ).With the passing of time,it has become easier to compromise passwords and therefore there is no guarantee of security by having a password,it has to be a secure one and the online service you sign up for should also offer an environment that maintains that level of security and  even  improves the level of security rather than diluting it and making the user's vulnerable. Many of us have been culpable of numerous password flaws which compromises our Cyber Security.The statement ' Do anything and everything and even hire a Cyber Security team but if your password is weak,none of it will matter ' says a great deal about the many underlying  issues  relating to Passwords other than say password length  and to an extension the whole Cyber Security Challenges.The aim of this eBook is to try shed  some light,understand and resolve most of these issues ,because in the words of Calvin Coolidge ( 30 th  US President )....' We cannot do everything at once,but we can do something at once '.I believe that we'll definitely have made an important step forward.
