UPDATE: Once again, this Apple iCloud "security" bug continues for me.
All my devices locked out again overnight, with the unpleasant surprise this morning 17 March 2021. This has been an ongoing issue since November 2020.
As for the suggestion to not enter the passwords, it would mean not being able to download apps on the App Store, and more importantly not being able to receive iMessage messages.
If I don't unlock the account and enter the password a dozen times on all devices, my phone number is not linked to iMessage or FaceTime anymore, on ALL devices. iPhone, iPad, Mac etc.
How is not entering the password and not unblocking my iCloud account a solution???
Once again, Apple broke something and doesn't care. This is a serious disruption of my enjoyment and use of several Apple devices I paid premium for, as well as iCloud service I pay a monthly fee for. And that's the level of service we get?? Being ignored for almost 6 months?
