Let's put it this way ; why do you need to have it? In this day and age, with identity theft being such a serious problem and the potential consequences that could result, one has to be careful to guard his passwords carefully. Sharing them with anyone, even a significant other, really isn't prudent. Not that you'd deliberately betray his confidence, but once he reveals them to you, there's always the chance that someone else could get a hold of them. The more people that have access to such information, the more troublesome it could become. Have you given him your information? I'd certainly advise you not to, for the reasons I've just described. I really don't think that this is a relationship issue, but rather sound and prudent guarding of one's privacy.
