MVP is a framework allowing websites to use diverse knowledge-based authentication schemes. One application is its use in conducting ecologically valid user studies of authentication under the same experimental conditions. We introduce MVP and its key characteristics, discuss several authentication schemes, and offer lessons learned from running 9 hybrid (lab/online) and 3 MTurk user studies over the last year.
