Sealed Lock Doesn't Work?

Or you can just save the 4k NX and not share your account with prick friends?

Seriously these items shouldn't be an excuse to go buck wild in sharing ur account info but used just as an extra safe guard.

I don't share my account, but that hardly stops me from wanting to lock my gear. Too much of my information is public knowledge, all it takes is someone bored enough with enough sheer CPU power to brute-force me now that they've removed secret questions and anything that isn't locked can be lost.

It's unlikely, but then again a single slip up from Nexon and all our accounts are wide open. I believe in minimizing risk.
