Docker Compose - user & password

[rivolity]

Hello, I have executed the following docker compose

---
version: '3.3'

services:
  cherry:
    image: haishanh/cherry:test
    container_name: auth_cherry
    volumes:
      - "/home/cherry:/data"
    environment:
      - JWT_SECRET=some-secret-string
      # this flag is important for remote-user feature to work
      - ENABLE_HTTP_REMOTE_USER=1
      - HTTP_REMOTE_USER_HEADER_NAME=Remote-User
    ports:
      - 8012:8000

When the docker is up, it requests a user and a password, which I can't find in your documentation. What is the default user and password, so I can authenticate to the app.
