How many combinations are there for a 8 digit number?
00,000,000 - 99,999,999 Since 9 is the highest single digit number if you were to make your password all nines then I believe that would give you the total amount of possibilities that the password could be. I may be wrong but I am almost positive I am not. If you were to try and guess a single digit password from 0-9 you would actually have ten different possibilities not nine because you include zero as a possibility. So I guess the accurate answer to this question would be 100,000,000 * * * * * The above answer is very seriously wrong because the person answering does not know the difference between a combination and a permutation. In a combination, the order of the digits does not matter. Thus 123 is the same as 321. The calculations are rather complex becuase they depend on the number of times a digit is repeated.

Password must Be 6 and 10 alpha numeric characters?
If a website (or other password-protected something or other) tells you that you must have a password of 6 to 10 alphanumeric characters, that means that your chosen password must be at least 6, but no more than 10, characters, which can be letters or numbers. "Alphanumeric" means letters and numbers, but not punctuation or other characters. So, "pass" would be too short, "thisismyabsurdlylongpassword" would be too long, and "@#*&@$!^" would not work because it's not alphanumeric. "P4ssw0rd" would be between 6 and 10 alphanumeric characters, although you should choose something less easy to guess than that.
