I don't understand the question. HMAC requires that both ends share a
secret key; does that help? What do you mean by verification? Do you
mean you want to make sure that's really Bob logging into your
computer, even when Bob might have intentionally given his password to
someone else? It sounds like you want something like DRM. What
exactly are you trying to do?
