Im betting that Huma probably likely wasnt on this computer very much like she states, HOWEVER she was probably on it enough to be on her email enough to where Weiner could log into her account. Being a Pervert, he likely had the back up plan fo getting black mail material in case his Dick was ever in a vice over his pervertedness (like now) and then use that info to soften his own blow while selling out his wife and Hillary in process with a plea deal. That would also explain The "Life Insurance" folder we have heard about.
