Login/logout missing from the WebGUI

Help docker

Hey!
So I've successfully set up Pi-Hole in Docker but I noticed that I when going to /admin I am automatically logged in without providing password.

I did docker system prune -a and docker volumes prune. Removed all bind volumes and started my stack again but it still gets me directly into /admin which isn't secure. Anyone knows what is going on?

EDIT: I noticed that it happens in both cases:

  1. When I use environment in Docker Compose file that specifies the password WEBPASSWORD: MyPassword
  2. When I do change my password using docker exec -it pihole_container pihole -a -p
2

This indicates you have set an empty password.

Are you using a volume mount with files from a previous container?
What happens if you start your container without volumes?

How come I do set up an empty password if I actually do set up a password?

Would you care to share your docker compose file? It might help us identify issues easier...

As a test:
What happens if you start your container without volumes?
