Why was my Apple ID account locked?
It always seems to be something with my Apple ID. My phones and computers randomly begin to prompt for passwords, forcing me to scramble to enter a correct password (in the morning, on my commute) before I can continue with my life.
Today, this happens again, already annoying — but then my account was "locked" after what I thought was a correct password entry (I copy and pasted it from a password security service). Needless to say, I have unlocked it, and also signed in successfully (with the exact same copy-pasted password).
Why was my account locked? Is there a security issue I should be made aware of? Why is Apple not communicating about this?
