The traditional world of authentication is alarmingly stateless -- it starts with a challenge, ends with a cookie, and when the cookie expires it all starts again. The user is left as a perpetual stranger, with no reputation, no history, no hope for a better experience. But there are several interesting ways that a little bit of shared information can change how users are treated. Pamela Dingle will walk through simple changes in approach that can have a radical effect on what a user might be asked to do, and how they are asked to do it. This will not be a theoretical talk -- methods demonstrated will be actionable recommendations.
