Reset password email sent when i didn't request for it

You can't track the phone that requested it.

Someone may be trying to sign into your Apple ID. You might want to consider changing your password and making sure it is a strong one. You can also add 2 Factor Authentication to your account for more security. If the attempts continue, you might want to consider a name change.

There's a long, recent thread about this on Reddit:

https://www.reddit.com/r/applehelp/comments/udxf7p/a_password_reset_request_was_sent_from_a_device/

Many Mac users started getting these notifications, repeatedly, numerous times a day (including me) for the past few days. Apple Support is not acknowledging it's a widespread issue -- not via this Support Community, not via phone calls to Apple, not via Apple Senior Support representatives. I am not sure what Apple could do to stop the notifications, because ...

Possible explanation: A recent MGM Resorts data breach, containing zillions of email addresses. Hackers who have this data are attempting to sign into the Apple Cloud -- and you get that notification. They don't necessarily have your password, which is why they are requesting a password reset. Do not use the sent link to change your password! And, changing your password will not stop the hacker from attempting to get into iCloud with your email address. Hopefully you already have a secure password impossible to guess. Hopefully after trying without success they will give up and move on to the next email on their list.

It would be nice if Apple would post something more than simply "you should probably change your password."
