Password Possible Options Calculator
This calculator is designed to give number of possible options for a password of up to X characters long, with a minimum of Y characters required, from a possible pool of Z characters. The length is the potential of the field; most are 8 characters but you may change as needed. Most passwords are a minimum of 4 characters but our default is zero (0) meaning you don't have to actually have a password. The character pool is composed of numbers and letters. If the password is only numbers, the potential character pool is 10 (0-9). If the password is only letters, the character pool is 26 (A-Z) upper or lower case accepted as the same. If upper and lower case are different, the character pool is 52 instead of 26. If the pool is alphanumeric, add 10 to the character pool; each group is additive. If your password allows for keyboard entered characters, such as $, @ or the underscore character, that adds 32 more characters to the possible pool. Do NOT consider spaces; we consider those based on the minimum number of characters required. Enter the values then click on Calculate. The maximum number of password possibilities for the values you entered is returned. If you had forgotten your password and were trying to guess it, and you guessed a different password each try, this the the maximum number of attempts until you guess it correctly. It does not mean it will actually take you that many tries; however, it could. Since we are dealing in probability, it is probable that the number returned will be larger than you expected and will probably be in scientific notation.
