Do you concern about unauthorised access to your Google Mail account?
GMail has an in-built solution for this issue.
At the bottom of your GMail page, you will find “Last account activity” followed by “Details”.
Click on “Details” link which will show your recent GMail account access.
From this, you will be able to find out if and when unauthorised agents accessed your mail.
As shown in the above image, you can find “AccessType”, “Date and Time” including the “IP Address”.
If your Google Mail account is currently being accessed from another location, this table will list the other session(s) in the “Concurrent session information” table.
If you find a suspicious or simultaneous access, then you can sign-out all other sessions, except yours from this session window. Then you can make necessary steps by changing the password/security question to avoid unauthorised access.
This is an excellent service provided by GMail. This will help you to protect your GMail account from unauthorised use.
