Proof by knowledge authentication techniques include traditional text passwords, visual passwords and graphical passwords. The paper compares these three techniques using an experiment. A total of 100 users participated in the experiment. After getting informed about the new authentication methods, users created their own text, visual and graphical passwords. Then they tried to confirm them correctly and finally they answered in a comprehensive questionnaire that the authors have created. Analyzing those data, they concluded that the text passwords that were created are predictable and very vulnerable to attacks. Visual passwords attracted users very much, especially those that are over 45 years old, although the passwords that they made are really easy to be cracked.
