Most of us put a lot of effort into finding free Wi-Fi, but public Wi-Fi networks have their own share of problems—particularly that it’s very insecure. Even if a Wi-Fi network has a password, other people on the network could see what you’re doing, or—if they were so inclinded—steal personal information and passwords. Luckily, there’s a lot you can do to stay safe: make sure sharing is turned off, use HTTPS whenever possible, and run your traffic through a VPN. Follow this guide for the details, and you should be a-okay.
