This command is what worked for me for the credential manager:
git config --global credential.helper "/mnt/c/Program\ Files/Git/mingw64/bin/git-credential-manager.exe"

I don't works anymore, the files is now in other place.

Hi! I suppose you're referring to the git credential manager file.
As per the documentation, you need to use a different path based on the version of Git you're running.
