Strange pop-up message
Out of the blue this morning, I saw this in a pop-up dialog box: "com.apple.WebKit.Networking.xpc wants to sign using key "Apple ID Authentication 2015-07-23 GMT-04:00" in your keychain. I've denied it twice because I don't know what it is. What is this? Is it legit? Thank
MacBook Pro (13-inch Mid 2012), OS X Mavericks (10.9.5)
