What Type of Security does iPhone Wi-Fi use?

WPA2 Personal (AES) is the recommended security for iPhone using a Wi-Fi network. But this can vary based on whether it's your own Wi-Fi router or an open Wi-Fi internet connection, like in a coffee shop, college, school or work place.

If your iPhone or iPad is connected to office or public Wi-Fi then it's best to encrypt your device's internet connection for optimum security. You can do this using a VPN compatible with both iPhone and iPad.

It uses whatever the wi-fi transceiver requires.

That depends on the wireless router. Most of the time its WPA2 but some use older types such as WEP and WPA.

It depends on the type of security being broadcasted by the hotpoint or router, 9/10 these days I'd say WPA2

Its not a matter of the iPhone its a matter of the connection you are trying to connect to. Whether it would be, WEP, WPA, WPA2 or unsecured.
