There is no such standard identification available.

Good luck.  People have been trying to solve that delemna for *years*.

One way would be to use an ID number from the machine's physical hardware,
such as a network card MAC address, hard drive serial number, etc.  However,
if the user needs to change the hardware for any reason, the password will
become invalid and they will have to receive a new one.

Another option would be to generate an ID number dynamically independant of
hardware, such as a GUID.  That way, even if the hardware changes, the GUID
remains the same.  However, that would require you to store the GUID
somewhere, and if something ever happens to that stored value, the password
becomes invalid as well.  Plus the stored value could be copied to another
computer, unless you encrypt it with something unique to the machine, but
then you're back to the issue of changing hardware invalidating your data.
