Not Taking Care on Public Wi-Fi
Most modern web browsers let you know whether you’re connecting to a website over HTTP or HTTPS — just look for a lock or security icon next to the address bar. Even if you don’t know the specifics of HTTPS encryption, you’ll want to make sure to pay close attention to that security icon.
If you connected to a website over HTTP, or an unsecured connection, an attacker might be able to intercept your passwords and login credentials. This is much more of a concern over public Wi-Fi, so we recommend avoiding any sensitive or financial browsing when you’re on unsecured Wi-Fi. No matter what, be sure to use a VPN when browsing on public Wi-Fi networks.
