2. A method for forming a pronounceable security password according to claim 1, further comprising the step of: determining if consecutive characters of said first pronounceable word segment correspond to a first word segment portion, within said plurality of first word segment portions, and if the transition number of said corresponding first word segment is less than said first threshold transition number.
2.
