Thanks for the suggestion, that's what I will check when she's awake, for now I'll like to be able to use the datas to find out "exactly" from where the account was accessed and how often, what google shows in Gmail as Location (IP address) isn't very accurate. I guess they have the exact datas, I don't just know what to do to get them....maybe I should just try emailing someone from their security team.
