Online security without the myths
Someone pays for a free VPN. If not you, then your data. This section has two guides: how safe public Wi-Fi is and why free VPNs are dangerous.
Where the real threats are
Most trouble online starts not with a hack but with trusting the wrong thing: a fake login page, a free app, an open network in a café. So security is mostly about habits: checking the site's address, installing apps from official sources, not typing passwords on someone else's network without encryption.
An encrypted connection closes one specific threat — interception of traffic on the way. It won't save you from a fake site where you typed your password yourself, or from a malicious app on your phone. That is what the guides in this section cover.
Public Wi-Fi
A network in a café, hotel or airport is shared by everyone connected to it. The hotspot owner and others on the network can see which sites you contact, and a fake hotspot with the same name can intercept all traffic. HTTPS protects page content but doesn't hide where you go. What is really risky on an open network and what isn't — in How safe is public Wi-Fi.
Free VPNs
All of a device's traffic goes through a VPN. A service that charges nothing makes money some other way: ads, selling browsing data or what it puts into the app. Before letting someone's server into your traffic, understand how it earns. The breakdown is in The risks of free VPNs.
What to check right now
The password generator creates a random password and checks an existing one for breaches — the password never leaves your browser. Domain WHOIS shows when a site was registered and who its certificate is issued to: a young domain on a "well-known shop" is a reason to stop before paying.
