This brilliant new feature, which
Microsoft has dubbed Wi-Fi Sense, doesn’t share your WiFi network password per se — it shares an encrypted version of that password. But it does allow anyone in your Skype or Outlook or Hotmail contacts lists to waltz onto your Wi-Fi network — should they ever wander within range of it or visit your home (or hop onto it secretly from hundreds of yards away with a good ‘ole cantenna!).
“For networks you choose to share access to, the password is sent over an encrypted connection and stored in an encrypted file on a Microsoft server, and then sent over a secure connection to your contacts’ phone if they use Wi-Fi Sense and they’re in range of the Wi-Fi network you shared,” the FAQ reads.
