wait so lets say i was to hack in to someone else's account, does that mean that my name will come up on the list?
i like the idea though
No, your IP will show up on the login history of the hacked account.
Many people change their IP everyday so it could be quiet complicated, but when you see that there were some failed logins from an IP, you could check if the IP logged into someone elses account and thus see who the hacker is.
