Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
That depends upon what information was asked for... and, when. If you were asked for info when you logged in, perhaps. If it was just a popup at a seemingly meaningless time, sort of randomly happening, then that's probably a fake or 'phishing' scam.
But it depends upon the exact circumstances. Let me know, and I will advise you further.
