Many studies reflect that today's younger generation spends a considerable amount of time online whether for doing their homework or playing games. However, the authentication schemes for this user group has received negligible attention. When exploring alternate authentication mechanisms for children, we decided to reduce the password burden and involve parents in the authentication decision. We chose to explore whether a parent-child password manager was a good choice for achieving this goal. We started with our 'Keep A Secret' prototype, a parent-managed password manager for children. On the next iteration, we designed 'KinderSurf', a parental consent mechanism based on the OpenID concept. We conducted two user studies for evaluating the prototypes. These user studies revealed areas for improvements, but overall both parents and children like the idea of using parental consent to log in.
