Abstract
A system receives a request to authenticate a user and determines a first set of cell identifiers of a card matrix to associate with the user. The system receives a first factor, which comprises a first set of received cell values corresponding to the first set of cell identifiers of the card matrix. The system further determines a first set of stored cell values corresponding to the first set of cell identifiers of the card matrix and compares the first set of received cell values to the first set of stored cell values. The system also receives a second factor, which is different than the first factor. Finally, the system determines that the user is authenticated based at least in part upon the comparison of the first set of receives cell values to the first set of stored cell values.
