This thesis explores how cultural factors impact password-sharing attitudes of Bangladeshi people. We first proposed "Emics-Etics for Usable Security" framework to incorporate cultural factors in security design. We then conducted a literature review that laid a foundation for applying an Emics approach (culturally specific) to address password-sharing in Bangladesh. To understand password-sharing in Bangladesh, we followed the Emics approach and Grounded Theory method to conduct and analyze interviews of 25 Bangladeshi participants. We found four cultural forces (gender, religion, social norms, and political context) that impact password sharing. We then present our interview-data based password-sharing model that identifies connections between perceived identity and stages of password-sharing, and describe the tensions that arise.
