Boingo offers a secure signup and authentication process. To ensure your connection is secure once you're online, you should make sure that the sites you visit are SSL-secured sites (https://...). Additionally, VPN services will encrypt all the data you send and receive.
If you're interested in an additional layer of security for your Wi-Fi connection, we recommend Boingo Passpoint. Passpoint offers the highest level of public Wi-Fi encryption, called Wi-Fi Protected Access version 2 (WPA2™) Security. It immediately finds and connects to the correct Wi-Fi network for you. Authentication is 2-way between your device and the network.
The free Passpoint profile installs in seconds and, once you're in range, gets you online automatically -- just like at home. You'll automatically connect at 150k locations, including thousands of Spectrum WiFi® hotspots! To get Passpoint, visit http://www.boingo.com/about-passpoint.
