Windows 8.1 request to “Enter your most recent password”… Legitimate

notificationspasswordsphishingwindows 8windows 8.1

I have a desktop computer that I keep at a location that I rarely visit anymore, but still use occasionally. It has been sitting in Standby mode (or whatever it's called on Windows 8.x), but when I "woke it up" today, I received a notification from the machine:

Password Request

I've never seen anything like this before, and given that the machine has been in a hibernated state and not under my direct supervision (though in a locked room and possibly without an internet connection) for an extended period, I suppose it's possible that something could slip on the machine and create a fraudulent request for a password for a phishing scheme. A quick use of Google-fu did not yield a conclusive answer. Has anyone seen this before, and is it something I should comply with?

Best Answer

That's legitimate. You are logged with a Microsoft account (hotmail.com, live.com, outlook.com, etc). The password of your Microsoft account has changed since the last time you logged into this machine. Now that your machine woke up and got connected to the internet, it was notified that the password has changed, and it is asking you to enter the latest password, so other services that depend from this account are not interrupted, like Skype, Widnows settings synchronization, some Windows Store Apps, etc.
