Can someone PLEASE help me crack this code?
My husband changed our password. But he forgot what it is. There is no other way to retrieve this info other than remembering the password.
Its 4 digit. The first 3 digits are 2,5,8 (but might not be in this sequence) each number was keyed in only once. The last and fourth number is either a 1,4 or a 7. How many possible sequence could there be and what are they? Please help. Thanks!

For some reason, I don't believe you that your husband forgot the password. What are the possible ways to combine these numbers? Well the first digit is either a 2, 5 or 8. So that's 3 ways. The second digit is either 2, 5 or 8 but you already used up a digit in the first digit so you really only have 2 choices. Similarly, by the time you get to the third digit you only have 1 choice. So you have 3*2*1 = 6 choices for the first 3 digits. Now for each of those combination, you have 3 choices for the last digit, 1, 4 or 7. So you have 6 choices and 3 ways for each choice giving 6 * 3 = 18 total options. One of which is:
2 5 8 1. I'll let you find the rest.

There are 3! = 6 ways to arrange 2,5, and 8, and there are 3 possibilities for the fourth digit. So, there are 6*3 =18 possible passwords.
The first three numbers can be ordered as
2 5 8
2 8 5
5 2 8
5 8 2
8 2 5
8 5 2
Now match each of these with 1, 4, or 7 for the 18 possible passwords.

Hi 1989:) I have read the article and it is interesting. I don't feel qualified to judge it's value one way or the other but I am just a tad uneasy about it's (apparent) implication that Jerusalem should be somehow more significant than other sites in the mystery of the universe. I mean, what about Stonehenge or my favorite spot in the woods? Perhaps I read too much into the article and it's just my knee jerk reaction about the "chosen people" stereotype? Could be. MY bad, in that case. I do feel that some places seem to be somehow "different" than others for reasons that are not clear and that it's desirable to keep an open mind. I'd also like to point out to those who seem to feel that Sir Isaac Newton would be somehow "above" such an idea that he was known to be very interested in Alchemy, something that would be considered a pseudo-science today. For anyone who ever looked at the visible light spectrum and had a hard time finding indigo....don't feel bad. It doesn't exist. Sure, there IS a hue we call indigo but it's just a shade of blue folks. Newton stuck it in because the number 7 had great significance in the "magic" of alchemy. So, I still can't comment on the validity of the article due to my ignorance but I wouldn't discount it entirely and I can easily believe it of Newton (who obviously WAS a brilliant man) so I take it seriously and think it deserves further thought.

Get a proffesional to help you Bypass the password protection.
Ther are 256 possibilities for that code so it would be unwise of you to risk damaging watever it is or risk locking its system up for good.

There are 256 combinations of those numbers. You are just going to have to try them all. Sorry.
