Tower of Fantasy has multiple missions/quests that you need to complete for rewards.
It also has side quests, stories, cutscenes, bosses, and more.
The rewards you can get are in-game currencies.
One part of the quest is to find the Ruin D-02 password.
This is part of a side-quest in ToF.
However, some quests are hard to complete because their hints are vague.
In this guide, you’ll learn what is the Ruin D-02 password (and how to find the two coded clues) in Tower of Fantasy.
Ruin D-02 Password in Tower of Fantasy

The Ruin D-02 Password is “2887” for the electronic lock.
The hint of the password can be found by navigating to the first Damaged Terminal near the “Bandits”.
If you interact with the first Damaged Terminal, it will give you a Coded Clue.
The Coded Clue is “xx87” and you have to find out the first two numbers of the password.
The first two numbers of the password can be found by interacting with the second Damaged Terminal.
You can find the second Damaged Terminal by closing the valve and heading down the stairs.
When you interact with the terminal, it will give you another Coded Clue.
The Coded Clue is “28xx”—now you have the first and second part of the password!
After you’ve entered “2887”, go inside the room and activate the “pyramid”.
