Do you have an Android phone? Some interesting news I read this week was that an innocuous (on by default) setting on Android phones can save your Wifi passwords on Google’s servers. It also backs up all your app settings, bookmarks and so on. This isn’t that worrying - it could be considered a useful feature. However, the worrying thing is that these plain-text passwords aren’t encrypted using your account details - they are available in unencrypted form to Google employees.
