1. A method for securely managing passwords, comprising the computer-implemented steps of: retrieving a set of variable parameter rules, wherein each variable parameter rule includes a plurality of variable parameter values; selecting a variable parameter rule from among the set of variable parameter rules, wherein the selected variable parameter rule is related to a temperature reading; defining a first static password; defining a second static password; defining a third static password; storing the first static password, the second static password, the third static password, and the selected variable parameter rule to a storage area of a server; mapping the first static password to a first variable parameter value, the first variable parameter value including a first temperature range; mapping the second static password to a second variable parameter value, the second variable parameter value including a second temperature range that is higher than the first temperature range; mapping the third static password to a third variable parameter, the third variable parameter value including a third temperature range that is between the first temperature range and the second temperature range; receiving an input password as input from a user; determining a current variable parameter value associated with the selected variable parameter rule; determining whether the input password matches either the first static password, the second static password, or the third static password based on the current variable parameter value associated with the selected variable parameter rule; and authenticating the user based on the password validation.
