Hello: I'm using openvnp using sudo and root pwd. I receive this warning - I'm not sure I understand - is this to suggest that I should have somehow set up a password for access to local TCP ports?

WARNING: Using --management on a TCP port WITHOUT passwords is STRONGLY discouraged and considered insecure
Or is this referring to an openvpn configuration where openvpn needs user/pass to access?
I'm simply invoking openvpn by: > sudo openvpn vpnservconffile.conf
