Wuthering Waves’ Solitary Path quest is Yinlin’s introductory companion quest, which has you pairing up with her to assist Lirong and his doll daughter, Yuanyuan. While advancing through the quest, you’ll encounter a safe house locked behind a password, which you’ll have to solve before progressing.
Enter the correct password during the Solitary Path quest in Wuthering Waves
The correct password for the Solitary Path quest is 4123. To complete the puzzle, interact with the unlock mechanism on the cave wall and input these numbers to open the wall, allowing you to enter the safe house and investigate the area.
There are two ways to learn the solution for this password puzzle. The tricky way without immediate spoilers is to count the sparkling purple flowers surrounding you and Yinlin, starting from the ones she stands at. Doing this reveals that she is looking at four flowers and, by circling clockwise to each bunch of flowers, shows patches of one, two, and three additional flowers. Linking these numbers together results in the correct password of 4123.
Alternatively, you can ask Yinlin for the answer. If you ask her about the solution, she’ll tell you to try counting the flowers, as she has a feeling they’re the secret to finding the passcode. However, doing this also reveals the exact solution, so you won’t have to count them at all.
Regardless of your method of solving the correct password, inputting it into the wall device will open the entrance to the safe house, bringing you one step closer to completing Yinlin’s Solitary Path companion quest.
