A few weeks ago, I upgraded my iPhone to the latest iOS, which includes two-factor authentication; unfortunately, I entered by AppleID password incorrectly, which prompted my phone to demand that I reset it, which I begrudgingly did...Doing so unleashed a world of hurt! I first called AppleCare to ensure my phone hadn't been hacked--it wasn't--the new two-factor authentication was the culprit. I had to sync my iPhone, iPad and iMac. Ugh! After I did that, I discovered my contacts were now in triplicate on my iPhone. Oh, the horror! I just finished deleting the duplicates, not a very productive use of my time. To add insult to injury, I now have another password to remember.
