Improving Password Memorability, While Not Inconveniencing the User
2019
Abstract Passwords are the most frequently used authentication mechanism. However, due to increased password numbers, there has been an increase in insecure password behaviors (e.g., password reuse). Therefore, new and innovative ways are needed to increase password memorability and security. Typically, users are asked to input their passwords once in order to access the system, and twice to verify the password, when they create a new account. But what if users were asked to input their passwords three or four times when they create new accounts? In this study, three groups of participants were asked to verify their passwords once (control group), twice, and three times (two experimental gr…
Improving the security of multiple passwords through a greater understanding of the human memory
2016
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 me…
The Light Side of Passwords : Turning Motivation from the Extrinsic to the Intrinsic
2019
There are many good and bad aspects to password authentication. They are mostly without cost, securing many accounts and systems, and allowing users access from anywhere in the world. However, passwords can elicit dark side phenomena, including security technostress; with many users feeling negatively towards them, as they struggle to cope with the sheer numbers required in their everyday lives. Much research has attempted to understand users’ interactions with passwords, examining the trade-off between security, memorability, user convenience, and suggesting techniques to manage them better. However, users continue to struggle. Many studies have shown that users are more concerned with goa…
User experience and the security of graphical passwords
2015
Graafiset salasanat ovat lupaava vaihtoehto alfanumeeriselle autentikaatiolle. Älypuhelinten ja muiden korkea resoluutioisten kosketusnäytöllisten laitteiden määrä on kasvussa ja alfanumeeriset salasanat ovat kehitetty alun perin näppäimistölle syötettäviksi. Tarkkuutta vaativa kirjoittaminen ei tällöin ole välttämättä käyttäjälle kaikkein mielekkäintä. Graafisia ja alfanumeerisia salasanoja on tutkittu muistin toiminnan sekä käytettävyyden näkökulmasta. Tutkielma on tehty kirjallisuuden pohjalta käyttäen apuna erilaisia tieteellisia julkaisuja sisältäviä tietokantoja, kuten IEE Explore ja ACM Digital Library - tietokantoja. Tutkielman tarkoituksena oli kuvata ja tutkia tieteellisten artikk…
Optimālas lingvistiskās stratēģijas paroļu un pieejas frāžu veidošanai un pielietošanai
2018
Pētījumi par valodas lomu parolēs pārsvarā izskata tikai to drošības aspektu, jo likumsakarības lietotāju izvēlētās parolēs iespējo to efektīvu minēšanu. Šīs pētījums izskatīja paroļu lingvistiskus aspektus, to veidošanas stratēģijas, mentālus procesus, ko tās kopīgo ar parastu valodu, lietotāju zināšanu avotus, kā arī uz stratēģiju komponentu vispārējo ietekmi uz drošību. No preskriptīviem avotiem savāktas stratēģijas tika klasificētas pēc to komponentiem; lielākoties iekļaujot sevī paradigmatiskās kopas, kuru elementi var tiek manipulēti, kā arī veidot sintagmatiskās virknes. Aptauja parādīja, ka vairākums no 42 dalībniekiem izmanto neefektīvas stratēģijas, paļaujoties uz viegli paredzamā…
Framing Effects on Online Security Behavior
2020
We conducted an incentivized lab experiment examining the effect of gain vs. loss-framed warning messages on online security behavior. We measured the probability of suffering a cyberattack during the experiment as the result of five specific security behaviors: choosing a safe connection, providing minimum information during the sign-up process, choosing a strong password, choosing a trusted vendor, and logging-out. A loss-framed message led to more secure behavior during the experiment. The experiment also measured the effect of trusting beliefs and cybersecurity knowledge. Trusting beliefs had a negative effect on security behavior, while cybersecurity knowledge had a positive effect.
Enhancing the user authentication process with colour memory cues
2022
The authentication process is the first line of defence against potential impostors, and therefore is an important concern when protecting personal and organisational data. Although there are many options to authenticate digital users, passwords remain the most common authentication mechanism. However, with password numbers increasing, many users struggle with remembering multiple passwords, which affects their security behaviour. Previous researchers and practitioners have attempted to suggest ways to improve password memorability and security simultaneously. We introduce novel approach that utilises colour as a memory cue to increase password memorability and security. A longitudinal stud…
