Wi-Fi password sharing security on iPhone and iPad
iOS and iPadOS devices that support Wi-Fi password sharing use a mechanism similar to AirDrop to send a Wi-Fi password from one device to another.
When a user selects a Wi-Fi network (requestor) and is prompted for the Wi-Fi password, the Apple device starts a Bluetooth Low Energy (BLE) advertisement indicating that it wants the Wi-Fi password. Other Apple devices that are awake, in close proximity and have the password for the selected Wi-Fi network connect using BLE to the requesting device.
The device that has the Wi-Fi password (grantor) requires the Contact information of the requestor and the requestor must prove their identity using a similar mechanism to AirDrop. After identity is proven, the grantor sends the requestor the passcode which can be used to join the network.
Organisations can restrict the use of Wi-Fi password sharing for devices or apps being managed through a mobile device management (MDM) solution.
