1. A method for improving restrictiveness on using a software application, wherein the software application is configured to generate a dynamic identification code and wherein access to the software application is restricted by requesting a personal identification number (PIN) from a user, comprising:

  • using a device having a memory, wherein the software application is stored in the memory;

    requesting, from the user, to enter an original PIN, wherein the original PIN is not stored in the memory and any information about the original PIN is not stored in the memory;

    using the original PIN as a seed number to create a true encryption key;

    using the true encryption key to encrypt an application secret data into a ciphertext;

    storing, in the memory, the ciphertext; and

    wherein;

    any time the software application is accessed by any person, requesting a PIN from the accessing person, wherein the requested PIN is not validated by the software application;

    using the requested PIN, without any validation, as the seed number to create an encryption key; and

    using the encryption key to decrypt the ciphertext.
