How to verify account ownership for steam-linked? In order to unlink your nexon account from steam, you have to include a ID if you're above 18 to verify that your birthday is correct. Besides having a false birthday (though I do wonder about that, since I might've put a false birthday down hmm), I remember making another nexon account when launching through steam because I did not know I could link a pre-existing one. I don't even know what birthday this account has anymore. Would this get in the way for unlinking my account? I am unsure of what to do, since I think I might have put down the wrong year for my birthday. Any help is appreciated, thanks!
