AppleID locked and forced to change multiple times
I am using three iphones under my AppleID (Two iphone7, one iphone 10) that are in different locations/countries. Recently it happened that when starting the phones in the morning, at least one of my devices (iphone7) is unusable and tells me that my Apple ID has been locked for security reasons and that I have to verify plus set a new password. After I changed it thinsg work, BUT now this froced change happens ever morning (last 3 consecutive days)... Anyone can help to understand where the issues is? Much appreciated.
