Help users adopt strong passwords by using the
generatePassword method. Passwords are generated from a criteria of five different input options;
allowSymbols. By default, the generator will generate passwords of 20 characters, but will not allow a user to generate a password that is less than six characters. If all options are marked false, the password generator will apply all options, the same as if all options had been marked true, resulting in at least one character from each option.
