Strange iCloud password request
Today I started receiving a strange dialog box requesting my iCloud password associated with my Apple ID email address.
I did update my Skype application today, and it asked to use my contacts. Is this why I am being asked for my iCloud password? How can I stop this password request? And if this request is coming from Skype, would it be better if if identified what my iCloud password is being requested?
Thoughts on this?
