By now you've heard all about the new Wi-Fi Sense feature on Windows 10. A month ago we warned you it was coming, and now it's here. On one hand, it's a pretty convenient feature, but on the other it could be a security risk if you're not careful. Imagine any or all of your Facebook friends getting full access to your wireless network! So how does Wi-Fi Sense work?
Basically, it's a feature that lets your friends (including Facebook friends if you choose to allow it) sign into your Wi-Fi network without the encryption key. If that sounds horrifying, just know that it's not that bad. It's definitely more secure than it sounds. In fact, it was designed to make wireless access both easier and safer for you back when it was first released with Windows 8.1.
Wi-Fi Sense was built to make it much more convenient to get onto a friend or friendly business' wireless network. Instead of just giving your friends your Wi-Fi password, along with full access to your router configuration and your whole network, your friends will never be able to see or know your password. On top of that, it's much more convenient than typing in a long, complicated password on a touch screen.
If you have Wi-Fi Sense enabled, and so does your friend, they just show up and log in automatically as soon as they're within range. Now, it can't be just anyone. Wi-Fi Sense will authenticate your Outlook and Skype contacts by default. It can also do it with your Facebook friends, but you have to choose to allow it. Plus you also have to choose to share your network.
