Wi-Fi password-sharing feature in Windows 10 raises security concerns

Blair Hanley Frank | July 2, 2015
With the launch of Windows 10, anyone who walks into your house and gets your Wi-Fi password for their PC could potentially let all their friends onto your network, thanks to a new feature that has ignited controversy online.

Wi-Fi Sense doesn't work with networks secured using 802.1X, which is often used by enterprises to keep their networks on lockdown, so that should give some small comfort to network administrators.

Ultimately, people who want to make sure that their Wi-Fi network is unavailable to Wi-Fi Sense users can rename it to include "_optout" at the end of the SSID. For example, a network called "foobar_optout" would be ineligible for sharing through Wi-Fi Sense, while one that's just called "foobar" would be usable with Microsoft's sharing feature.

If you don't want to change your network's name, Microsoft suggests that you manually enter the network's password for your guests and make sure the checkbox to share the network is turned off.
