How To Check If Some Intruder Is Accessing Your Gmail Account

If you are suspecting that some hacker or an intruder is accessing your Gmail account without your knowledge then Gmail has a feature called Last Account Activity that will provide you with information about your recent account activity. The information includes the last time that the account was accessed, the IP address from which the access was made, as well as the date and time, it enables user to check and verify that the login is indeed valid and legitimate, and whether there is another person using the Gmail account without your consent and knowledge.

To access the Last Account Activity history, click on the Details link at the end of the Last account activity line at the bottom of any Gmail page as shown in the screenshot below. It will open a new window showing the recent sign-in records from last few hours onwards.


Once you open the Details link, you will see Activity information window which offers immense information, including user’s current IP address, so that user can know easily which session is opened by him, and if there is another login session to Gmail that does not occur on his or her computer.
