Widespread adoption of touchscreen phones among blind users seems inevitable. Blind users face significant challenges in terms of accessibility and inclusion in the smartphone environment, despite prevalence of screen-readers and assistive software. This can lead to a variety of security and privacy risks while using smartphones. This paper presents qualitative research findings of a user study about security and usability aspects of smartphone usage by 51 blind smartphone users of age 18 to 40 years in a metropolitan city of India. We discuss the challenges users face, their coping strategies, and key insights that could inform design for security and usability.
