Although there have been numerous studies investigating password usage by neurotypical users, a paucity of research has been conducted to examine the use of authentication methods used by individuals with cognitive impairment. In this paper, we report a longitudinal study that investigates how individuals with Down syndrome interact with three user authentication mechanisms. It confirms that many individuals with DS are capable of using traditional alphanumeric passwords as well as learning other authentication methods. Contrary to previous belief, the result suggests that mnemonic passwords may not be easier to remember for individuals with DS during initial usage.
