Confirm iPad / iPhone passcode to keep using iCloud
Why am I getting a message on my iPhone and on my iPad, in Settings, that reads “Confirm iPhone / iPad Passcode” and then says I need to confirm my iPhone / iPad passcode to keep using iCloud. This passcode also protects access to data stored in iCloud. I haven’t changed any settings or passcodes and my access to iCloud, along with iCloud backups, appear to be occurring normally. I’ve tried turning off the devices, but the message stays on. What should I do about this and why is it happening?
