How do you test the usability and security of your design ideas? Jeremiah Still walks us through research he and his team conducted on graphical authentication, where users select system-generated images for their passwords.
In this episode, we talk about:
- Where the fields of cognitive psychology, security, and user experience meet.
- Why Jeremiah and his team chose to investigate graphical authentication.
- How they cleverly incorporated testing both usability and security in their two-part study.
- The importance of research around learnability: is it easy for users to learn how to use your new authentication schema?

What is Human-Centered Security?
Cybersecurity is complex. Its user experience doesn’t have to be. Heidi Trost interviews information security experts about how we can make it easier for people—and their organizations—to stay secure.
