To start off, if you hover your mouse over your IGN. You'll get something like this.
Now the problem with this, is what is being shown for me. Which I have been through live chat and back for. It shows my password, which I have since changed. The Nexon Employees I've talked to tell me that what is shown is my Account ID, which cannot be the case as I have never used my password as an Account ID. That is just silly. Now Nexon cannot change Account IDs or do anything to remove this from being shown. You see, if I were to stream which I do sometimes to guidlies etc. My old password could get leaked pretty easily without a ridiculous overlay. Here, have a picture of such overlay.
As such you see where I'm going with this suggestion, I'm proposing Nexon remove this feature completely. Why would you want anyone to see your Account ID when you hover your mouse over your character anyways, along with situations like mine where my password ended up as my Account ID somehow. This is honestly a pretty bad security risk, and something that I cannot get changed. I'm stuck with my old password just being leaked.
If a Nexon employee wants to look into this more, I talked to GM Akkadiro Ticket Number: 666924. It's marked as solved, but nothing was actually solved, there was just nothing they could do for me.
