I've been playing runescape since 2010. Out of the 3 accounts I've had 2 of them have been hacked or compromised in some way. I have had to make a new account again as my 2017 account was compromised leading to nasty surprise when I attempted to log a few days ago. My account was banned for something I never did during a time period where I was not playing runescape at all because I was studying for college exams. I have now set up an authenticator but I would be interested to know if there is an extra layer of security I can add to my account on top of the authenticator I am currently using.
