An important goal of the authentication system is to provide support to users in selecting better passwords thus increasing security by expanding password space. The use of click -based pass words leads to the selection of passwords which can be easily hacked. We use persuasive technique to influence the user in selecting the password in random manner rather than using a particular sequence.
