Nine Chronicles uses blockchain technology to run, and it doesn't have a central server or a central authority. While blockchain technology has its pros, it also has its cons. We can't change passwords the same way we change passwords everywhere else, and we also can't just log in on new devices as easily as in traditional platforms and games.
Private Key is important because:
- It is one of only two means a player can recover their account in case they had to change device.
- It is the only means a player can change their password.
- Private Key ownership entails ownership of the entire account, including characters, currency, and items.
These are the reasons we always remind everyone to back up their Private Keys securely and never to share with anybody else. (Members of Planetarium or CST will never ask for your private key). Losing your Private Key is akin to losing everything you own in the game; no one can help you recover it.
