Apple ID password
My different Apple devices require a different ID password.
I have an iMac, a MacBook Pro,an iPad and a new iPhone 13 which seems to have caused the problem.
I had to put in a new Password for my new device (I don't know why) and two of my devices need the new password and two only operate on the old password (including any new phone!).
Can anyone tell me how I can standardise these devices on one password which I thought should have been done seamlessly on iCloud.
