Query: Investigation of the Effect of Fear and Stress on Password Choice
  (Extended Version)   Background. The current cognitive state, such as cognitive effort and
depletion, incidental affect or stress may impact the strength of a chosen
password unconsciously. Aim. We investigate the effect of incidental fear and
stress on the measured strength of a chosen password. Method. We conducted two
experiments with within-subject designs measuring the Zxcvbn \textsf{log10}
number of guesses as strength of chosen passwords as dependent variable. In
both experiments, participants were signed up to a site holding their personal
data and, for the second run a day later, asked under a security incident
pretext to change their password. (a) Fear. $N_\mathsf{F} = 34$ participants
were exposed to standardized fear and happiness stimulus videos in random
order. (b) \textbf{Stress.} $N_\mathsf{S} = 50$ participants were either
exposed to a battery of standard stress tasks or left in a control condition in
random order. The Zxcvbn password strength was compared across conditions.
Results. We did not observe a statistically significant difference in mean
Zxcvbn password strengths on fear (Hedges' $g_{\mathsf{av}} = -0.11$, 95\% CI
$[-0.45, 0.23]$) or stress (and control group, Hedges' $g_{\mathsf{av}} =
0.01$, 95\% CI $[-0.31, 0.33]$). However, we found a statistically significant
cross-over interaction of stress and TLX mental demand. Conclusions. While
having observed negligible main effect size estimates for incidental fear and
stress, we offer evidence towards the interaction between stress and cognitive
effort that vouches for further investigation.
