To further protect your account, we suggest players to enable the Character Lock function.
Before choosing a character, you may select a character lock for each. Please leave Old Char Password blank if you are using this function for the first time. Next, select an individual password (separate from your account) for your character. If you wish to disable this function, simply provide your Old Char Password while leaving the following fields blank.
If you forget your character password, please file a ticket, providing your account information.
