Yo, I’ve been there! To answer your question, yes, others can connect to the proxy you set up, but you’ll need to forward the port on your router. If you’re using a home network, your ISP might be blocking it too, so keep that in mind.
For testing, use a tool like [YouGetSignal](https://www.yougetsignal.com/tools/open-ports/) to check if the port is open. And yeah, definitely set up some kind of authentication in Squid to keep things secure.
