Experts are often asked for advice about password management, but how do they manage their own passwords? We conducted interviews with researchers and practitioners in computer security, asking them about their password management behaviour. We conducted a thematic analysis of our data, and found that experts described a dichotomy of behaviour where they employed more secure behaviour on important accounts, but had similar practices to non-expert users on remaining accounts. Experts’ greater situation awareness allowed them to more easily make informed decisions about security, and expert practices can suggest ways for non-experts to better manage passwords.
