How to check if your Gmail has been hacked
Method 1 – How to know if someone else is using your Gmail account
If your Gmail account has been hacked and is used by someone else you can easily track your Gmail account by looking at the Last Account Activity which you can find at the end of the email list. It is mentioned in small letters on bottom right. Beside it, the time when your Google account was last used is also shown. Looking at the time you can figure out as you will know the time you last logged in to your account. If it is not matching then surely your Google account is compromised. To get more details click on the Details link given just below the Last Account Activity.
Details link will pop up a new browser window which will provide you with Browser, Location (IP address), Date and Time for the last 10 activity (sign in) in your account. Looking at this you can figure out the location of the user accessing your account.
Method 2 – How to know if someone else is using your Gmail account
Another way to do the same thing is click on your picture at the top and click on Account. Select Security Tab in Account settings page. On right hand side you will see a box showing Recent Activity. Click on View all Events link. This will show the same information with addition of the some other activities like when did you change your password, turned on/off 2 step verification and a few more. It will be represented as shown in picture below.
By looking at this you can check if your Gmail account has been hacked and is being used by someone else. If you find any suspicious activity go ahead and change your password and use security settings to make your Google account more secure.
