This invention describes a cell phone, or other wireless device (henceforth known as "device"), to transmit sound (audible and inaudible) alphanumeric code in any language, special characters or symbols or graphic or pictures or videos or any combination thereof, to an on-line account at a web server that is equipped with a compatible digital transceiver card and software driver and/or firmware for the operation, management and maintenance of this system. Upon verification of the transmitted code or sound, by the web server, access is granted. The said server then transmits a randomly selected new code of any combination of the codes or sounds stated above to the device for storage. The said transmission from the web server cannot be stored in any other device. The device has a menu item and/or numeric code for each on-line account of the user.
