Get a security key, people. Even if it's only for the 100 cartel coins per month (which you even get as a free-to-player) and the exclusive vendor.
It's really no inconvenience to enter the number, and while I've never worried about my MMO accounts, being pretty much certain it's safe is nice.
Do you know where Security Keys are for sale in the EU and/or generally outside of the US? As far as I'm aware, Security Keys are not currently for sale outside of the US.
Perhaps Mr. Philip_BW could help with this?
