22. 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, 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) being categorized into one of at least two categories based upon a transition number corresponding to the number of said second word segment portions within the associate set of second word segment portions, comprising the steps of: identifying one or more selection categories from said at least two categories, wherein the transition number associated with each of said first word segment portions categorized within said one or more selection categories equals or exceeds a first threshold transition number; selecting a first one of said plurality of first word segment portions categorized within said one or more selection categories, wherein selection of any one of said plurality of first word segment portions categorized within said one or more selection categories is of substantially equal probability; selecting a first one of said plurality of second word segment portions from the set of second word segment portions associated with the 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 categorized in a non-selection category.
27. A method for forming a pronounceable security password according to claim 22, further comprising the steps of: identifying a first word segment portion, within said plurality of first word segment portions, categorized in said one or more selection categories and corresponding to consecutive characters at an end portion of said first pronounceable word segment; selecting a second one of said plurality of second word segment portions from the set of second word segment portions associated with said corresponding 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; and combining said first pronounceable word segment with said second selected second word segment portion to form a part of said password; wherein said generated pronounceable security password includes said second selected word segment portion only if consecutive characters of said part of the password fail to correspond to those of said plurality of first word segment portions categorized in the non-selection category.
