How would I go about creating an application that consisted of a login page where the user should provide a unique username, password, and 3 security questions. The password should be at least 8 characters in length and should include at least one upper case letter, one number and one special character. The three security questions should be from one of 10 prepared security questions that you design. For example, have them select from a list of 10 questions and provide their answers to 3 they select.
