What is Password ?

Password is an encrypted combination of numbers, letters and special symbols, typically between 4 to 16 characters that allows authorized access to a computer, interface or system. The password helps ensure that unauthorized users do not access the computer. In addition, data files and programs may require a password.

Since the invention of computer password in 1960s by Fernando Corbato, it is most trusted, reliable and secure method that is used everywhere today. Everywhere on the internet, computers, ATM, mobile phones passwords are used for keeping our accounts and data safe. Usually password is based on ASCII pattern that is the American Standard keyboard layout.

Today even after developing advance security methods we are still using password and no other security measure can ever replace it. All the social sites even the Facebook uses password for securing it's users account.

The password system works usually with a username that differentiate each account with the help of Primary Key that makes every username unique. Every valid combination of username and password authenticates the user and provides access only if the person is authorized user of the account. Now the question comes how the password works? Password works with the help of a two way system that works with front end as the main GUI part that can be a webpage, program, computer etc and the back end that is a database that contains all the username and passwords. When a user enters a username and the password the system check it in the database if it is valid combination or if it is then the access is granted and if not then system deny for the access. PHP is the most commonly used programming language that is used for the connectivity of front end to the database.

The encryption of the password makes it more secure and difficult for an unauthorized person to hack the password.
