1. A system comprising:

  • a machine-readable medium storing thereonmachine instructions for an Application Program Interface (API), which when invoked, cause a processor system of a machine to implement the API, the API having an argument for a passcode generator and a user ID, the processor system having one or more processors; and

    another set of instructions, which when invoked, cause the processor system to compare a submitted passcode to a generated passcode;

    wherein the passcode generator is a value derived from user information; and

    wherein the passcode generator is a value from which deriving the user information is expected to be intractablewherein the other set of instructions include instructions for causing one or more processors to generate a generated passcode from a new passcode generator;

    wherein the other set of instructions receive the passcode generator from the API, and generate the new passcode generator from the passcode generator.
