Google Knows Every Wi-Fi Password in the World
This article points out that as people are logging into Wi-Fi networks from their Android phones, and backing up those passwords along with everything else into Google’s cloud, that Google is amassing an enormous database of the world’s Wi-Fi passwords. And while it’s not every Wi-Fi password in the world, it’s almost certainly a large percentage of them.
Leaving aside Google’s intentions regarding this database, it is certainly something that the US government could force Google to turn over with a National Security Letter.
Something else to think about.
