Usability of Long Passwords in Web Application

Abstract

As the advancement and progression in internet technologies and computers, one of the main issues which came in the limelight is web security. Every person in the world is using the internet as their daily routine but they are not aware of the risks of it. People are doing an online transaction without knowing that if they don't use some security mechanisms, someone can steal their session ids and can empty their accounts. There are many types of authentication mechanisms available like passwords, biometric (voice, face and fingerprint) etc, but passwords are easy to implement and easy for users to understand. Passwords also have many drawbacks like if passwords are short or a dictionary word, it can be easy guessed or brute-forced by an attacker. It is a difficult task to create and remember passwords that are hard for an attacker to guess. Markov chains can be used to create password. So in this paper, we are also proposing a usable password generator which generates usable and memorable passwords for users.
