PwdRsch

Hi, I'm Bruce K. Marshall. I've been conducting and gathering research on passwords and authentication systems since the late 90's. I started the PasswordResearch.com site as a way to share my collection of information and to encourage more collaboration between academics and IT practitioners.

I'm here to continue learning about the questions and problems people have with authentication as well as contributing my own experiences. You can also find me on Twitter @PwdRsch.
