A user can get access to its account only by means of username and password in this sense the security of user account is only dependent on the password of user. Hence, it is important that user should keep their password confidential. In many systems people select their username and text passwords when registering accounts on a website. The matter becomes worse when users would choose easy-to-remember passwords (i.e., weak passwords) even if they know the passwords might be unsafe. Therefore, it is important to take human factors into consideration when designing a user authentication protocol.
