alternatives to text-based password authentication. We provide a comprehensive overview …

Graphical passwords were proposed as an alternative to overcome the inherent limitations
of text-based passwords, inspired by research that shows that the graphical memory of …

This paper presents an integrated evaluation of the Persuasive Cued Click-Points graphical
