Abstract
Time-varying passwords for user authentication are disclosed. Example methods disclosed herein for password generation include obtaining a base password including characters, determining a first character position of the base password at which a first time-varying data element is to be inserted to determine a time-varying password, the first time-varying data element to be computed based on a time-varying parameter, and determining a first offset to be applied to a value of the time-varying parameter to compute the first time-varying data element. Example methods disclosed herein for password evaluation include accessing a base password including characters, applying a first offset to a value of a time-varying parameter to determine a first time-varying data element to be inserted at a first character position of the base password to determine a time-varying password, and comparing the time-varying password with an input password to perform authentication based on the input password.
