Hi guys,

is there a way to get a unique computer number for every PC that logs into a website? We can't track IP addresses because they change, also not cookies, because they can be deleted.

we just want to make sure that members in our site do not share passwords. and to do this, we envision just limiting the members to the computer numbers that they register to the site.

if this is not possible, are there other ways?
