dc.description.abstract | Multiple passwords are an increasing security issue that will only get worse
with time. One of the major factors that compromise multiple passwords is
users’ memory, and the behaviors they adopt to compensate for its failures.
Through studying memory elements that influence users’ password
memorability, we may increase our understanding of the user and therefore
make proposals to increase the security of the password authentication
mechanism. This dissertation examines the human memory to understand
password security behaviors; and moreover, develops new theories and revises
prominent memory theories for the password context. This research employs
memory theories to not only increase the memorability of passwords, but to
also improve the security of them by means of three studies that examine users’
beliefs and awareness (metamemory) about how their memory affects their
password memorability and insecure password behavior; and look to
increasing password memorability through improving learning (repetition
through verification), and retrieval (through uniqueness). Empirical
longitudinal studies collecting objective and subjective data measuring
password recall (over 10000 passwords), memory interference, memory
performance, memory beliefs, user convenience, and insecure password
behavior. Through collecting objective password recall data, the results of these
studies challenge users’ preconceptions about justifying their adoption of
insecure password behaviors. Furthermore, it challenges the assumption of
trade-offs between password security, memorability and user convenience
found in previous password research. In meeting the objectives of the
dissertation, this research has significant practical implications for
organizations and individual users. Through a greater understanding of the
human memory this can inform users to adopt better password security
practices. The implications of these results suggest how to increase password
memorability, how to decrease password forgetting, and how to decrease
insecure password behaviors and the consequences of such insecure behaviors
(such as security breaches). | |
