Why is my ID password rejected?
I tried to buy a movie and my password was rejected, despite being unchanged. I went thru the hoops to change it to a new one. Then I get all the messages on my iMac, iPad, and Apple TV asking for the new password because they are all set to the old one and were working fine. iCloud immediately reacted. What is going on with Apple ID? This happened once before and I thought it was my mistake - now I'm not so sure.
iMac, OS X Mavericks (10.9)
