Tiivistelmä

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 study examined in total over 3000 passwords that were created, learnt and recalled (password process) over a period of five-weeks. By adding colour to the password process, our results suggest that password memorability and security can be increased simultaneously. Through giving the user the option of choosing the colours (compared with colours being preselected), encourages users to create more personal and meaningful memory cues when creating their passwords. Additionally, colour also provided another security parameter by increasing password entropy. These unique results have practical implications for researchers and practitioners that could positively impact password security, and the financial losses suffered due to password security breaches.
