The number itself deliberately doesn't tell you much, so crackers can't use it for clues on where their attempts are going wrong. –Tony Hopkinson Jan 4 '14 at 16:10 8 @David if you see a duplicate question in SO, then mark this as such. Just because the answer is easy to come by, doesn't mean it doesn't belong on SO.

The most common cause is that this userID hasn’t b
