Don’t expose it over the Internet, local network access only, is the easiest but also limits you to accessing it only at home.
You could use something like tail scale or setup your own wireguard server to keep it still local-ish but still allow trusted people access.
Reverse proxy with auth of some kind if you plan to expose it to the Internet.
