Use Public Wi-Fi More Safely

Public Wi-Fi is not automatically dangerous, and modern HTTPS encrypts the content of most web traffic. The bigger everyday risks are connecting to an impersonated network, entering information into a fake captive portal, ignoring browser warnings, exposing local sharing services, or using an unpatched device.

Before connecting

• Ask staff for the exact network name when possible.
• Avoid networks with confusing duplicates such as “Hotel Guest Free” and “Hotel_Guest_Free_5G” unless the venue confirms the correct one.
• Turn off automatic connection to open networks.
• Install system and browser updates before traveling.

While connected

• Use websites and apps that show a valid HTTPS connection. Do not bypass certificate warnings.
• Be cautious when a captive portal asks for more than basic access information.
• Disable file sharing, network discovery, printer sharing, and AirDrop sharing with everyone.
• Use your cellular connection for highly sensitive activity when practical.
• A trustworthy VPN can reduce what the local network and internet provider can observe, but it does not make a fake website trustworthy or stop you from entering information into a scam page.

After leaving

1. Disconnect from the network.
2. Forget it if you do not expect to use it again.
3. Turn off auto-join for hotel, airport, conference, and store networks.
4. Review any unexpected login alerts that appeared during the trip.
