Because of the whole system of needing to link accounts, and outsourcing, I have an idea for better account security which also helps in case of needing to transfer accounts between devices.
How about creating a unique username and password for TWD:RTS. So you can log out of one device, and login to another if needed. It will solve the hassle of needed to go through support, and could strengthen account security.
Let me know what you think of this idea @JB.Scopely or @GR.Scopely , and I got the idea from https://forums.scopely.com/t/ingame-account-security
