Google: All Your Passwords Are Belong To Us
 

Forget the FBI and NSA snooping. Beware of Google collecting your Wi-Fi passwords and doing it with your permission. Be afraid, be very afraid. This is all possible because of a feature that lets you back up and save your data to Google's servers. This includes the obvious, like backing up your phone book and calendar, but it also snags your Wi-Fi passwords in the process.
