It certainly is gut-churning to see the new message if you don’t know what it means. When I read the patch notres, I was worried that SE was foolishly opening up the doors to possible account theft, but it telling the server to kick your character so you can log back in certainly is a nice feature, and will probably end up with a lot less people getting kicked from parties when they D/C in a dungeon.

Still, it would probably be best if people with similar concerns for their accounts get authenticators. Changing your password periodically is a good idea on top of that, as extra security helps.
