Abstract

Text passwords are the ubiquitous method of authentication, used by most people for most online services. Many people choose weak passwords that are vulnerable to attackers who simply guess all the passwords within the most probable password spaces. This paper describes a lightweight password creation mechanism that uses Persuasive Technology to influence users to create stronger passwords. Results from a pilot study show that our Persuasive Text Passwords (PTP) prototype system successfully influenced users to create and remember more secure passwords.
