Activity of account in Gmail

Clicking the Details link next to the Last account activity line at the bottom of any Gmail page shows information about recent activity in your mail. Recent activity includes any times that your mail was accessed, using a regular web browser, through a POP client, from a mobile device, etc. We'll list the IP address from which the access was made, as well as the time and date.The IP address column is also useful. If you always or most often sign in to Gmail using a single computer, your IP address should be the same, or start with the same two sets of numbers (for example, 172.16.xx.xx). If you're seeing an IP address that differs greatly from your usual IP address, it could either mean that you've recently accessed your mail from a different location, or that someone has accessed your mail. Your current IP address is displayed below the Recent activity table.If your mail is currently being accessed from another location, we'll list the other session(s) in the Concurrent session information table. This could mean that you simply have another browser window open with Gmail loaded, or that your home computer is logged in to Gmail while you're accessing your mail from work. If you're concerned about any concurrent access, you can sign out all sessions other than your current session by clicking Sign out all other sessions.You'll need to change your password and your security question. The first step is to read our suggestions on choosing a good password to make sure that your new password is secure. Then, follow the instructions in How do I change my password? to update your password.
