Apple's iOS 10 will give you a warning when you're connected to an unsecured Wi-Fi network
Apple has been mum about it so far, but it appears that iOS 10 will provide iPhone and iPad users with a warning when their device is connected to an unsecured Wi-Fi network. Don't expect to see a flashing screen with a siren, or a Dennis Nedry type pop-up saying "Ah ah ah. You didn't say the magic word." Instead, the warning will appear when you head to Settings > Wi-Fi.
Under the Wi-Fi network's SSID, you will find the words Security Recommendation. Tap the 'i' button and you will be warned that the Wi-Fi network you are using is unsecured. The actual warning reads, "Open networks provide no security and expose all network traffic."
