Save repository password in file for Windows

Hello, in post here : Password retrieval command · Issue #807 · kopia/kopia · GitHub

All those are great ideas, simply not implemented yet.

On macOS and Windows password is not stored in a file but in OS-specific keychain tied to user login password (you can store it in a file if you wish).

But how do I save the repository password in a Windows file?
thanks in advance
