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.

The Light Side of Passwords : Turning Motivation from the Extrinsic to the Intrinsic
Woods, Naomi (Association for Information Systems, 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 ... -
Too many passwords? : How understanding our memory can increase password memorability
Woods, Naomi; Siponen, Mikko (Academic Press, 2018)Passwords are the most common authentication mechanism, that are only increasing with time. Previous research suggests that users cannot remember multiple passwords. Therefore, users adopt insecure password practices, such ... -
Improving the security of multiple passwords through a greater understanding of the human memory
Woods, Naomi (University of Jyväskylä, 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 ... -
How Memory Anxiety Can Influence Password Security Behavior
Woods, Naomi; Siponen, Mikko (Elsevier, 2024)Password reuse and modification are insecure password behaviors that are becoming increasingly prevalent as users are obliged to remember more passwords to access various digital services. Many users adopt these risky ... -
Improving Password Memorability, While Not Inconveniencing the User
Woods, Naomi; Siponen, Mikko (Academic Press, 2019)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 ...
