Abstract
A method for authenticating users over networks includes requesting a one-time password, entering a personal identification number into a communications device, and retrieving a replaceable shared secret stored in the communications device. Moreover, the method includes generating a hashed personal identification number from the entered personal identification number, combining the hashed personal identification number with the replaceable shared secret to generate a modified shared secret, and generating a one-time password with the modified shared secret and the time of requesting the one-time password.
