This presentation was delivered at the IA Summit 2008 in Miami, FL. The wide-spread adoption of web-based services has helped people organize information, connect with loved ones, and share data through an electronic medium. This convenience, however, has spawned a massive proliferation of single-purpose user profiles, closed data repositories, and endless login credentials. Not surprisingly, people are quickly becoming less tolerant of experiences that require large quantities of personal information upfront.Deciding what information to ask a customer when creating an account is a literal balance between user needs and business needs. Users want to protect their privacy and provide as little information as possible. The business, on the other hand, wants to learn who their customer is, and ask as many revealing questions as possible. In this session, I will draw from my experience in redesigning the Yahoo! registration and account recovery systems. I will also show examples from other web sites, and suggest techniques to apply toward common IA and Interaction Design challenges faced in designing membership frameworks. This session will discuss the following topics: <ul><li>Making registration painless for your customers</li> <li>Encouraging accurate and truthful data entry</li> <li>Keeping the bad guys out but allowing for password recovery</li></ul>
