Access to file system

I need access to the file system using Putty so I can add a custom integration folders and files. I used to have this and I am certain that I used to be able to log in as root with no password. But it doesn’t work any more.
Can anyone please point me in the right direction why this might be?

My setup:
Core 2024.11.0
Supervisor 2024.11.2
Operating System 13.2
Frontend 20241106.0

Custom integrations should be in the config folder (or homeassistant as it is called these days) under custom_components. You do not need root access for that, nor would you want to. For many installation tyoes the files would get lost on updates if you put them in the wrong place.

Thanks, I do understand that. What I do want to know is how can I get access to the config folder? I do need to log in to the file system in some way.

Other ways of doing this is the addons/samba/DOCS.md at 3c20eb004da4ec84792a20fca34c6a7cca3da7fe · home-assistant/addons · GitHub or Home Assistant Community Add-on: Visual Studio Code
