How to know if someone has hacked your Gmail account? Hack of your account of Gmail is one of the worst things that can take place, particularly for the reason that given the amount of services that Google offers, get someone else's password Gmail means you have access not only to our mail, but potentially to our location (if using Latitude), to our profile and other portals (if using Profiles), and even our credit card (if using Checkout). Moreover, when you access your Gmail account and do nothing, the person with access to our account may, for example, access to passwords and critical data by simply asking for a "password reset", for example, other sites web. Can anyone give me brief info about this? Thank you in advance.
