While images or emojis offer good memorability when used in an authentication method, inherently graphical data are highly susceptible to shoulder surfing attacks. An authentication system incorporating emojis was proposed and designed, which offers resistance to shoulder surfing attacks. The proposed system implements emojis in place of numerics in the reference method, DragPIN, and adds cue questions. The methods are compared in terms of performance and memorability, through user testing. The proposed authentication system was found to be successful at resisting shoulder surfing attacks. After 4–6 weeks, memorability was also higher in the proposed method compared to the reference method.
