Password restriction policies and advice on creating secure passwords have limited eects on password strength. In- uencing users to create more secure passwords remains an open problem. We have developed Persuasive Text Pass- words (PTP), a text password creation system which lever- ages Persuasive Technology principles to inuence users in creating more secure passwords without sacricing usabil- ity. After users choose a password during creation, PTP improves its security by placing randomly-chosen characters at random positions into the password. Users may shue to be presented with randomly-chosen and positioned charac- ters until they nd a combination they feel is memorable. In this paper, we present an 83-participant user study testing four PTP variations. Our results show that the PTP varia- tions signicantly improved the security of users' passwords. We also found that those participants who had a high num- ber of random characters placed into their passwords would deliberately choose weaker pre-improvement passwords to compensate for the memory load. As a consequence of this compensatory behaviour, there was a limit to the gain in password security achieved by PTP. |
