In my case, it wanted the passcode on another iPad and not a Mac ( I have two iPads, an iPhone, Apple Watch, two Mac connected to my iCloud account as primary accounts / keychain sync enabled on all).
I have not seen the follow on passcode/password page ever until today. When you reset all settings or restore a backup from iCloud (or set up a device as new), the Keychain / iCloud and local USB trust pairings are removed and you should be prompted to trust the Mac when it connects to your iPhone.Īfter the trust setting dialog pops up (if you are connected over USB), there is now a screen that asks you to enter your iCloud password to finish setting up the iOS device.
