iPad was automatically removed as a trusted device from two-step verification for your Apple ID
Last night (31 March 2015 at about 7:30pm) I received three emails from Apple stating that my iPad was automatically removed as a trusted device from two-step verification for your Apple ID (email address). I received this message on three separate emails - one for each of the amiss on file with my Apple ID . At the end of the email message it said "If you did not erase this device or if you believe an unauthorized person has accessed your account, you should reset your account password immediately at My Apple ID."
I was very surprised to see this message implying that somehow my account had been compromised. Regardless of what might have happened, I RESET my password. Incidentally, this PW set also made my App Specific PW for Outlook invalid so I had to request another App Specific PW to male Outlook resume working with 2FA. But I went to the safari My Apple ID page directly, rather than clicking on the web link in the email as a protection against "phishing."
Unless someone had got access to the inner workings of Apple ID and 2FA, I do not see how this could have happened unless there was an error made by the Apple ID system. Any access to my Apple ID account would have required verification using one of my verified devices.
Has anyone got an explanation of what might have happened? Lets' hope this is a very rare occurrence. I see there have been earlier post on a similar subject but none have had a plausible explanation of what might have happened and why.
