Abstract

Access to computer systems is most often based on the use ofalphanumeric passwords. However, users have difficultyremembering a password that is long and randomappearing.Instead, they create short, simple, and insecurepasswords. Graphical passwords have been designed to tryto make passwords more memorable and easier for people touse and, therefore, more secure. Using a graphicalpassword, users click on images rather than typealphanumeric characters.. In this paper we describe theDAS(Draw-A-Secret) scheme, its security characteristics,and the empirical study we carried out comparing DAS toalphanumeric passwords. In the empirical study participantslearned either an alphanumeric or graphical password andsubsequently carried out three longitudinal trials to inputtheir passwords over a period of five weeks. The results showthat the graphical group took longer and made more errorsin learning the password, but that the difference was largelya consequence of just a few graphical participants who haddifficulty learning to use graphical passwords. In thelongitudinal trials the two groups performed similarly onmemory of their password, but the graphical group tookmore time to input a password.
