I don\'t know a whole lot about computers, so I was wondering, is it possible to hack into someone\'s yahoo account? Like, could two people be in your account at once?
Yes, two people can be logged into yahoo at the same time without eachother knowing of the other\'s presence. Yahoo doesn\'t have a "someone else is already logged in with that name" feature, and they just let them in. Multiple people can be logged into a yahoo account at the same time.
