Effect of Cognitive Effort on Password Choice

چکیده
This paper reports on a lab experiment with 100 subjects which is the first to investigate the impact of cognitive effort and depletion on the choice of user passwords. Two groups of 50 subjects each were asked to generate a password. One group was cognitively depleted, the other was not. Password strength was measured and compared across groups. We find that subjects who are cognitively depleted create worse passwords than undepleted subjects. Surprisingly, subjects who report mild cognitive exertion create better password than undepleted subjects. We are interested in discussing how cognitive effort impacts authentication as well as how to negotiate the cognitive demands of password procedures to best support users.

Effect of Cognitive Depletion on Password Choice Extended Technical Report
Background. The Limited Strength model [3] of cognitive psychology predicts that human capacity to exert cognitive effort is limited and that decision making is impeded once high depletion is reached. Aim. We investigate how password choice differs between depleted and undepleted users. Method. Two groups of 50 subjects each were asked to generate a password. One group was cognitively depleted,...

Background: Cost-benefit decision-making is a one of the decision-making models in which the animal achieves a final benefit (reward) by evaluating the cost (effort or delay). The role of different brain regions such as nucleus accumbens in this process has been proven. Orexin is a neuropeptide expressed exclusively by lateral hypothalamus area neurons and orexin-producing neurons project their...
