For iCloud Keychain how do I change the phone number needed to verify the code being text to me? The number it was sent to is an old phone number of mine that I don't have access to.
iPhone 6s, iOS 9.3.2
Try this from another thread I seen.
On iOS go to Settings > iCloud > Keychain and tap to button to disable iCloud Keychain. (you will be asked to delete or keep passwords on device) i chose delete....
Then enable it again and in pop-up chose Reset iCloud Keychain, on confirmation pop-up chose Reset
In new pop-up Use iPhone Passcode as iCloud Security Code? chose Use Passcode
Enter your passcode (4 digit) and then chose country and your new phone number
Although, to "Reset iCloud Keychain," I assumed meant to clear the data and essentially set up a new, blank Keychain. Not so. Strangely, after essentially bypassing the security regimen, setting a new passcode and verification number, I see my cards, passwords and other data have been restored. Maybe it's all about the iCloud account and that master password. Or maybe it's a bug. With Apple, we'll never know.
