摘要：This paper presents a survey of proof by knowledge authentication techniques (text passwords, visual passwords and graphical passwords). Both new methods are more memorable, as people have to remember images and not characters and graphical passwords are also more secure. A total of 100 users participated in our survey, who after getting informed about the new authentication methods, they answered to the questionnaire that we have prepared. Based on their answers all users have many passwords for their everyday needs and they try to select passwords that are not only memorable, but also secure. Unfortunately, they can not deal with proper password selection and they become victims of dictionary attacks. Understanding this situation, participants were very positive in learning more about the new authentication methods. They found both techniques memorable and friendly - visual passwords at most, but they found graphical passwords a bit more complex and difficult to learn how to use them, something that they can overcome with small practice.
