Lionel OgdenI have had a few problems of late with my Apple ID. For the last several years I have had the same ID and password which I had stored on my Mac. Two or three times recently my password has been rejected and I have changed it only for it to be rejected again a few months later.
When this happened again earlier today I thought that I would check if something was amiss by ringing Apple Support. Previously I have had very good help from Apple support but this time was not one of them. It took ages to get them to accept that I needed help with Apple ID passwords. Even when they took over the screen to show me what to do the arrow was wandering all over the screen and I needed them to repeat everything several times. When I then tried to log in to iCloud using my newly changed password, the advisor said that I was using the wrong password and that I should use the machine password instead.
I know I am getting long in the tooth but this was confusing.
The blurb about Apple ID says that it is used for iCloud as well as almost everything else Apple.
