- People should use strong passwords. This three-year study tested a range of visual nudges designed to edge people towards stronger password choices. We discovered a nudge strategy that worked: we gave people an incentive to choose stronger passwords: extended expiry periods. We combined three interventions: (1) a nudge, (2) the incentive and (3) a reminder every time they logged in, for a 6-month period. Over 600 participants chose significantly stronger passwords than they had without the nudge. This longitudinal study launched several follow-up research initiatives, commercial enquiries, and article in the Wall Street Journal.
