You have alnum, numeric, and alpha functions in your variable generators, but many sites (the good ones, anyway) require passwords to have at least one Uppercase, lowercase, numeric and special character. I've been getting around this by doing "{{alnum:10}}@123Ab" in order to make sure all my required character classes are covered. It's a bit of a hack and I think there should be a random string generator which is deterministically providing required characters.
