Stuart Schechter is currently the course lead for the usable security course in UC Berkeley’s Masters of Cybersecurity (MICS) program and the founder of DiceKeys. Schechter previously performed usable security research at Microsoft Research, MIT, and Harvard. Among his past research is work showing that it’s possible for the great majority of users to memorize 56-bit cryptographic keys. His research has helped debunk a number of once-popular security practices, including the use of security questions for account recovery, the use of site-authentication images (e.g. “SiteKey”) to fight phishing, and the use of password rules to prevent users from choosing common passwords.
