A few days ago I got a message on my Mac that my Apple account was locked and I had to change my password. I did that, but ever since then, using Apple products has become a nightmare. I have Mac, iPhone, iPad and Apple TV, I'm signed in all of these devices and they are synced via iCloud.
All devices are asking for password multiple times a day, applications also synced via iCloud (for example Notability) can't sync because they detect iCloud not available. Multiple restart happened, I deleted local files, I deleted caches and still not working as it did a few days ago. Why on earth I have to enter multiple times my password on a device when I assume it should be enough (I assume an auth server should be able to serve all auth related requests centrally) only once?
Does Apple lock user accounts frequently and force users to change passwords? If not, then is possible to get some info why they did it in my case?
My account has had this password for a few months, or half a year. It is in use on daily basis for work.
