My successfull attempts to Lakera's Gandalf game

Date: 2023-01-15

Welcome to my Gandalf password guide! 🧙‍♂️🔐

📜 This README lists the prompts I used to reveal Gandalf's passwords at each level. It also includes the corresponding answers. Some were inspired by other users.

🔄 Be aware: the game may have changed since this was written. Some prompts might not work anymore.

🧩 Prompts from higher levels often work in lower levels, too. However, I didn't fully test this. Remember, LLMs are not deterministic. There are always different ways to find the passwords.

🎉 Happy hacking! 👾
