Logon Character Pin Window
From FlyFF WIki
This new security system has been on the table for a while. It should help to protect our beloved Flyff items from those devious hackers lurking around.
- Default Pin is "0000". Once in game set your bank pin. You should now benefit from this heightened security.
- If you already have used your bank (deposit) in game, then you have to use that bank pin in order to log in on your character(s).
