How many of your passwords do you actually know? Now, how many of those passwords are already on the black web? We are living in a fascinating age of transition from personalised passwords dependent on text inputs and our memory to more advanced access solutions.  To help us navigate this evolution, we talk with Justin Richer. Justin is a technologist working on a wide variety of projects and problems throughout the internet. Justin is the founder of Bespoke Engineering, an independent consultancy specialising in internet security and identity. He is the author of OAuth in Action along with Antonio Sanso. He is the editor of several security standards including http message signatures, GNAP, OAuth dynamic client registration, OAuth token introspection, and vectors of trust, and has contributed to dozens of others. He previously spent 15 years at the MITRE Corporation contributing to many different efforts, including collaboration, identity, serious gaming, and security research programs.
