that depends on how many different characters you have to choose from.
if the password was made of numbers only then you would have 1030 different combinations.
Passwords are technically permutations, not combinations. There are 104 = 10000 of them and I regret that I do not have the time to list them. They are all the numbers from 0000 to 9999.
im assuming that any charcter can be a number or a letter: (24letters*10 possible numbers)^(4 digits)= 3317760000 possible combinations.
When trying to work out how many different combinations there are, you need to know how many options there are for each value. If the password only contains lower case letters, then we have 26 options for each value. For each letter in the password, there are 26 options, so the total number of possible options is 26x26x26x26x26x26 or 266 This equals 308,915,776 so there are 308,915,776 possible different combinations of six letters.
36*36*36*36*36*36
With a Latin alphabet of 26 letters and the 10 digits 0...9, and allowing for repeats, you get: 36^4 = 36 × 36 × 36 × 36 = 1,679,616 combinations. If you were to include both lower and upper case characters, the number of possible combinations goes up (due to 26 lower case letters + 26 upper case letters + 10 digits = 62 characters to choose from): 62^4 = 14,776,336.
Mix as many combinations as possible. Here is one example: f_@mW^1O3+
We can use 36 characters for each of the slots in the combination. Therefore, we have 36^11 possible combinations, or 131,621,703,842,267,136 combinations.

Passwords allow only authorised people to view the information. Without the password - the data remains secure. Passwords can be any length (usually a minimum of five characters) - and made up from numbers, letters and other characters. The longer the password - the more secure it is. For example... say you need a password of just numbers and letters... a five digit password would have a possible 60,466,176 combinations. However a ten-digit password would have 3656158,440,062,976 possibilities !
Assuming any character can appear in any position, it makes 3620 = 13,367,494,538,843,734,067,838,845,976,576 or approx 1.337 x 1031 possible different passwords.
it is 26

It could be anything from 0000 to 9999 (10,000 possible combinations).

It depends what the password is for. A 'good' password should consist of at least 10 characters. It should be a mixture of letters and numbers - but NOT something that could be guessed by someone who knows you. For example - the password I use to access my bank account online... has ten characters - and comprises 6 letters and 4 digits. I have NEVER revealed it to anyone - which makes guessing it almost impossible !Whatever password you choose - it should be something that you can easily remember - but nothing too obvious. How abut the name of your first pet... plus the year you were born.Just for reference... a 10-digit alphanumeric password has...3,656,158,440,062,976 possible combinations !
