I've previously connected to a WiFi network on my iPhone but I have no way of finding out the password. Is there any way to recover the password after resetting my device to view saved WiFi passwords on the iPhone?
"after reset my device 'view saved wifi passwords on the iPhone' " answers your question I think? Do you have a mac that's connected to the same network? Then you can retrieve the password in the Keychain of the computer. (analogue for Windows systems)
