This option displays information about the latest access to your Gmail account along with the type of access (browser, POP, mobile, etc.), location (IP address), and date and time of access. By checking devices, time and place you can determine if someone has access to your account or not. If you see a suspicious and unexpected device, time or place, change your password and turn on 2-step verification
