Hi there, sure is. I suggest contacting either Game or Acyroma for retrieving ur password ( Discord private message, is the fastest way to reach them ). You can change ur linked-gold account to any other account u wish, this can be changed in:
Settings -> Edit Profile -> Annihilus account ( Type the name in this box ). Good luck!
