You may have been presented with a window that asked you to log in to your Xfinity or Optimum W-Fi account. There doesn’t seem to be any other public Wi-Fi networks around, so why do these networks show up so frequently? Companies, such as Xfinity, pay to provide complimentary Wi-Fi hotspots to their customers. These hotspots are placed in various public locations and allow up to five people to connect to it at one time. These networks are publicly accessible, which means that you should be careful about what type of information you provide or access while connected to the network.

While using a public network, you should never buy goods online, enter your credit card or banking information, send or read sensitive emails or documents, or type in any account information. If a malicious individual is on the network, he or she could easily see your every move online or compromise your device. If you’re worried about using public Wi-Fi, it might be best to change your phone’s settings so that your phone isn’t set to automatically join public networks.
