Overheard a guy at a coffee shop talking about public wifi risks and it clicked for me
I was waiting for my latte last Tuesday and this dude next to me was telling his friend how he used a VPN on his phone even for normal browsing. I always thought VPNs were just for torrenting or hiding from your ISP, not for everyday stuff like checking email at Starbucks. But he said something about how a lot of public wifi networks are unencrypted and someone could grab your login cookies with basic tools. I went home and actually looked into it, found out there are apps that let anyone on the same wifi see your traffic if you aren't careful. Now I run a VPN anytime I'm on a public network, even at the library. Has anyone else had a close call on public wifi or found a free VPN that actually worked decent without selling your data?

Oh boy, let me stop you right there on one thing. The idea that anyone on the same wifi can see your traffic with basic tools is true, but it's only half the story. Most websites nowadays use HTTPS encryption by default, so even on public wifi, someone sniffing traffic can't just grab your login cookies like it's nothing. They'd need to get past the encryption on the connection itself, which isn't as easy as it used to be back in the early 2000s. That said, I still run a VPN on public networks for the extra peace of mind, especially for sites that might have older security or for when I'm typing in credit card info. But don't think every wifi hotspot is a total free-for-all like some people make it sound. The real risks are more about man-in-the-middle attacks where someone sets up a fake wifi spot, not just sitting there with a packet sniffer on the same network.

Wait, does that mean all those times I panicked at the airport and held my phone weirdly over my head thinking it helped somehow were pointless? I gotta say, your point about fake wifi spots is what actually scares me more now. I've definitely connected to "Free_Airport_WiFi" without thinking twice before, and I bet half of those were just some guy in a hoodie with a laptop. I tried ProtonVPN's free version after that coffee shop talk and it's been alright, but the free tier limits how much data you can use so I only turn it on for important stuff. Still better than nothing though, even if I did look a little dumb holding my phone up like a Geiger counter.
