Google knows nearly every Wi: If an Android device phone or tablet has ever logged on to a particular Wi-Fi network, then Google probably knows the Wi-Fi password. Considering how many Android devices there are, it is likely that Google can access most Wi-Fi passwords worldwide. Recently IDC reported that 187 million Android phones were shipped in the second quarter of this year. That multiplies out to 748 million phones in 2013, a figure that does not include Android tablets. Many probably most of these Android phones and tablets are phoning home to Google, backing up Wi-Fi passwords along with other assorted settings. And, although they have never said so directly, it is obvious that Google can read the passwords. Sounds like a James Bond movie. Android devices have defaulted to coughing up Wi-Fi passwords since version 2.2. And, since the feature is presented as a good thing, most people wouldnt change it. I suspect that many Android users have never even seen the configuration option controlling this. After all, there are dozens and dozens of system settings to configure.
