it hasn’t so much as happened to your iPhone, but rather the passwords that have been used used on your iPhone have been found in data leaks elsewhere, or are passwords with other related password security issues.
This re-use or weak passwords or such is then reported to you by your iPhone, to allow you to know about and upgrade your passwords.
These password diagnostics are fairly common, particularly among those of us that have re-used passwords that were, well, weak, or those of us that have reused a password exposed by a password breach elsewhere.
Various websites and services that many of us have used—services elsewhere on the Internet—have become breached, the passwords then exposed, and the miscreants then try these same passwords in logins across the rest of the Internet. Including, for instance, re-trying these breached-elsewhere logins and passwords as Apple IDs.
One of my throw-away passwords from a dozen years ago that was still present in my password Keychain ended up (through corporate acquisitions) at a completely different Internet service long after a breach at the original service, and some schmucks then re-tried that old password, and (almost) got in. With few exceptions, we’ve all been bad with a few passwords, and the server breaches are making that more of a problem.
What to do? Pick a couple of the most serious reported issues each a day or two, and fix them, or delete the accounts if they’re no longer relevant to you and your needs, and work your way through the backlog of bad passwords.
