Use a VPN on public Wi-Fi networks

Passwordless public Wi-Fi is unencrypted, meaning your data can be intercepted while using it. Consider setting up a virtual private network (VPN) to encrypt your connection and shield your activities from prying eyes on public networks. Short of that, look for “semi-public” alternatives such as coffeeshop/restaurant Wi-Fi with a requestable password (usually on a receipt) from the staff.
