How to: Update a saved password for a Wi-Fi network on your iPhone


Instructions

Apple does not provide a way in iOS to update a saved password for a wireless network. Instead, you can tell your device to forget the network, and then set up the connection again.

We recommend submitting feedback to Apple at https://www.apple.com/feedback to ask them to add a feature to iPhones, allowing users to change the saved password for a previous Wi-Fi network connection.
