Keep receiving a password reset email.

In my case I don't think so. I think it's a fresh leak because this has never happened me before and not only is it my email address (constant password reset emails) but constant calls to my phone number associated with my Hotmail account.... You know those scam calls where they ring for 2 seconds without you answering hoping you'll call back and it'll give them access to your phone.... I've had calls from at least 7 different numbers from Zimbabwe and Ghana... I can't help but think this is linked to the email hacking attampts seen as this number is registered to my Hotmail account...

Just for clarification - this is happening to me as well but I suspect I know the reason it happens.

The e-mail that's being attempted to be accessed has been compromised in the past - in fact, it's probably featured in multiple data leaks; the most probable cause for multiple people having this issue within a close interval is that there has been a newer leak of old data or that new organizations got access to old leaked data and are attempting to get access to those accounts.

It's probably going through a list of thousands if not millions of addresses, so it probably tries X ways of getting in for each address for a few days and then moves on.

Either it's a fresh leak from Hotmail or it's some app people would have signed up to in mass amounts lately that have had a leak such as zoom or something

Yes.

Getting loads of Sync errors for multiple countries

What information needs to be entered in order to request a password reset?

Would a hacker only need to enter the Hotmail address?

Or does some other piece of personal information need to be entered.

(I don't want to actually try it to find out.)

Snap. Checked my sign in attempts and loads of attempts happening (and failing) but have had three password reset email codes in the last 24 hours now
