From Openkore Wiki
- storageAuto_password <password>
- Specifies your password for your in-game storage. Only used for passwords entered via special window in Ragnarok Online client, like on official servers. If NPC just asks for a number or string during generic NPC conversation, use storageAuto_npc_steps instead.
You don't have to set this option. If you leave it empty, OpenKore will ask you for you to choose when needed, providing short tip and/or list of possible values.
