With the increasing use of computer and smartphones by children, their online safety has been of major concern due to their limited security knowledge and skills. User authentication is pivotal for their security protection, where a body of work focused on children's password practices. The insights from these studies highlight children's lack of awareness and skills in creating a strong password. However, there is a dearth in existing literature to understand the scopes of designs for encouraging and empowering children towards strong passwords. As we begin to address this gap, we leveraged the power of storytelling to foster user attachment, encouragement, and empowerment. To this end, we adopted a systematic approach through a series of studies. First, a focus group session with three experts whose research primarily focuses on children contributed to build the narrative of a story, followed by a participatory design study with 20 children (aged between 8 and 12) to understand their preferences and perceptions of design components for the visual depiction of that narrative. The insights from focus group and participatory design led to the design of 'Story', a digital storytelling based design representing password advice for children. We also created the baseline designs and compared them with Story in a within-subject survey with 44 children aged between 8 and 12. The findings from our study unpack the efficacy of storytelling, leading us to offer guidelines for future research in these directions.
