Can Other People Connect to the Proxy I Set Up? How to Control Access Safely

Hey everyone!
So, I just set up a proxy for myself, and now I’m kinda wondering... *can other people connect to the proxy I set up?* Like, I don’t want randos hopping on it, y’know?

I followed some tutorials, but they didn’t really explain how to lock it down. I’m not super techy, so I’m a bit lost. Do I need to set up passwords or something? Or is there a way to whitelist only my devices?

Also, if someone *does* connect, can they see my stuff? That’s lowkey freaking me out lol.

Any tips on how to control access safely? Would really appreciate some advice!

Thanks in advance! ✌️
