User Experience Evaluation in the Creation and Use of Graphical Passwords for Authentication in Mobile Devices

摘要

This article aims at present the results of a user experience evaluation for the creation and use of graphical passwords on mobile devices as a way to improve usability and security aspects in authentication. The authentication method proposed was defined in a project called Multimodal Biometric and Graphical Authentication for Mobile Devices. These assessments were carried out with thirty users during a period of fifteen days using a prototype that offered a repertory of eighty icons divided into four categories. All users were able to remember their eight-icon password and claimed having a good use experience with this authentication method.
