- Vince Manis brought this up on RISKS a few years back. At the time he had a
- machine which had a three digit, user-selectable code. One of the responses
- gave a numeric string which contained all possible combinations of three
- digits: the poster estimated, based upon the length of time you had to enter
- the code, that at most two calls would be necessary to "hack/crack" the
- machine.
-
- My own machine has a four digit, factory set code. It is rendered slightly
- more secure by the fact that the company makes several models, not all of
- which have remote access, but which all sound identical.
-
- One machine I bought for a company I was contracting for had a single digit
- security code. My daughter's machine is even worse: it has a three digit
- code, but any of the three digits, repeated three times, is valid for access!
