What is my iCloud passcode?
I am trying to sign on to iCloud on an iPhone. I entered my iCloud password correctly. I then get a prompt asking for my iCloud passcode. I don't recall setting up an iCloud passcode. Is this different from my iCloud password? I tried entering my device password and my iCloud password, but both were rejected. I logged into iCloud from my Mac and can not find any reference to an iCloud passcode. I already have 3 failed attempts and the docs say that with 6 failed attempts my device will be locked and I will have to reset it from a backup.
What is the difference between the iCloud passcode and the iCloud password and is there any way to reset the iCloud passcode if I do have my iCloud password?
iPhone 6 Plus, iOS 10.2.1
