Why people (don’t) use password managers effectively
A recent study by a team of CyLab researchers, including Pearman, provides some insight into how ineffectively people may be using password managers, potentially nullifying the benefits the managers are meant to provide.

Security and privacy need to be easy
In 2005, Carnegie Mellon hosted a first-of-its-kind conference that brought together researchers from dozens of universities and companies around the world with one mission: make privacy and security tools easier to use. That conference, the Symposium On Usable Privacy and Security (SOUPS), is holding its 15th annual meeting next month. SOUPS, as well as the entire usable privacy and security field, have deep roots at CMU.
