I have read that "ein" should be the password for level 6. But I don't know if this is correct. I'm at level 5 and can't find the password. Can you help me?

The password for 6 is Journal

Thanks but I am looking for the password for level 5

You have to travel in the 5 in the storm in the future there you will find 3 parts that give the name Duttweiler. You have to find question marks on the screen like this

Hallelujah thank you very much
