24
If a password is 30 characters how many combinations are possible you have been out of school 50 years so please no formulas about X zillion will also be good?
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.
How many possible alpha numeric combinations are there using all letters for 4 characters?
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.
