Ways to Check if Your Gmail Account Has Been Hacked
Gmail is one of the most popular and most widely used free email clients available.
But is also frequently targeted by hackers. Much of the time, users might not even realize that their Gmail account has been hacked.
There are some actions which a hacker can take that will allow him/her to be able to read your email without logging into your Gmail account. These include using Gmail for mobile, the IMAP feature, email forwarding, and so on. While Gmail's "last account activity" feature can be helpful, there are also other methods of looking into the safety of your Gmail account and keeping it protected.
