Yeah, I get that. It'd be nice if they'd let me remove it after logging in with it, though. I mean, if someone's already got the key, there's no point in keeping it in place, after all. Ah well. Thanks for the useful response, anyway.

Is there a way to do this once it's enabled, or am I stuck with it from now on? I enabled it just to see what was in the store, but none of it is interesting until I reach higher levels. I don't really feel like I need the extra security--my password system is pretty solid, and I'm the only user of the computer on which I play. As such, having to enter the key every time I want to play is more of a hassle than anything else right now.
