A few simple habits can make a noticeable difference. Avoid entering sensitive information on unfamiliar networks unless the connection is protected, keep your device and browser updated, and use strong, unique passwords with two-factor authentication. A VPN can also add another layer of privacy, and if you need a temporary option, you might look for a free VPN code from a trustworthy source. It is also worth disabling automatic Wi-Fi connections so your device does not join unknown networks unexpectedly.
