1. A method implemented on a computing device for forming a pronounceable security password using a plurality of first word segment portions, each having at least one character, and a plurality of second word segment portions, each having at least one character, with each of said plurality of first word segment portions (i) having an associated set of one or more said second word segment portions, each said second word segment portion within said associated set being different from others within said set and being combinable with said associated first word segment portion to form a pronounceable word segment and (ii) having a transition number corresponding to the number of said second word segment portions within the associated set of second word segment portions, comprising the steps of: selecting a first one of said plurality of first word segment portions, wherein selection of any one of said plurality of first word segment portions is of substantially equal probability; selecting a first one of said plurality of second word segment portions from said set of second word segment portions associated with said selected first word segment portion, wherein selection of any one of said second word segment portions within said associated set of second word segment portions is of substantially equal probability; combining said selected first word segment portion and said selected second word segment portion to form a first pronounceable word segment; and generating a pronounceable security password including said first pronounceable word segment only if consecutive characters of said first pronounceable word segment fail to correspond to those of said plurality of first word segment portions having a transition number less than a first threshold transition number.

A method for forming a pronounceable security password according to claim 1, wherein said pronounceable security password is formed of eight or more characters.
