Appreciation post: Found a forgotten guest WiFi network with no password at a coffee shop in Tucson
I was at this little coffee shop near the university in Tucson last week, just doing some work. While I was checking my own hotspot setup, I saw their guest network pop up on my phone. It had no password at all, wide open for anyone. That's a big risk for people using it, especially if they're logging into bank accounts or email. I ended up telling the barista about it and they actually changed it to a password by the time I left. Has anyone else run into open networks like this and actually said something?
