摘要：Electronic communication is an emerging technique where we send information from sender to receiver in the form of E- Mail. To send and receive an Email, each user should have an ID. That ID must be locked with the unique password. The password is in the form of text. It may be alphabetical, numbers, alphanumerical and etc. Email servers provide the constraints to set the passwords, for the users. Even most of the servers secured, Black hat hackers hack the account and access the information. A graphical password is an authentication system that works by having the user select from images in a specific order, presented in a Graphical User Interface (GUI). The most common computer authentication method is to use alphanumerical usernames and passwords. This method has been shown to have significant drawbacks. For example, user tends to pick a passwords that can be easily guessed. On the other hand, if a password is hard to guess, then it is often hard to remember.
