This article on Password is re-posted with some revisions. 

Wikipedia's definition of a password as below:

"A password is a secret word or string of characters that is used for authentication, to prove identity or gain access to a resource (example: an access code is a type of password). The password must be kept secret from those not allowed access."

Passwords ensure the security and confidentiality of data that is stored on various workstations and servers

Passwords are one of the important things for any system. It will help you to maintain your identity so that others will not be able to view your account. You need to have a good password otherwise your password is likely to be hacked by others. Once they are successful in hacking your password they easily view your account. 

Generally, a password is made of many characters or digits and will not use any special character or a white space in between. In some systems passwords are case sensitive. Here you need to be extremely careful and remember to type the correct password accordingly. This is because some of the system will have some restriction and if you are mistyping the password repeatedly it is likely that your account will be denied access and you need to then go through the procedure that is in place in the system.

If you are going to choose a password which is not good then it means that your security of your account is not very good and there is always a fear that your account is going to be hacked and they will be able to access all the information that you have in your account.
