Windows 10 Shares Your Wi-Fi Password With Contacts

gsslay writes: The Register reports that Windows 10 will include, defaulted on, "Wi-Fi Sense" which shares wifi passwords with Outlook.com contacts, Skype contacts and, with an opt-in, Facebook friends. This involves Microsoft storing the wifi passwords entered into your laptop which can then be used by any other person suitably connected to you. If you don't want someone's Windows 10 passing on your password, Microsoft has two solutions; only share passwords using their Wi-Fi Sense service, or by adding "_optout" to your SSID.

    no guests with windows laptops on my wifi - i'm not going to change my ssid, microsoft style. ugh. i guess this issue will resolve itself after a short shitstorm.

      It seems that there is room for convenient router functionality that asks you this: 'A device with MAC address x requests access to your network: GuestLAN. Allow?'

      Handing out passwords to untrusted parties instead of tokens is archaic anyway.

      Most people can't be bothered to look at what their computer is doing before clicking an UAC window, you really expect them to properly opt-out of SSID passkey sharing properly?

      The Slashdot summary is pure FUD. In the article itself you can see an image of the settings, with a large checkbox to enable/disable sharing with Outlook, Skype and Facebook independently and it also has a large slider above those where you can disable it entirely.

      Did you read the box?

      Save on mobile data usage with Wifi Sense. Join in and get connected to WiFi. By using WiFi Sense, you agree that it can use your location.

      Who doesn't want to save on mobile data usage!? How many people will opt-out? Where does it say that by opting in that they are sharing their Wifi passphrase with everyone they share to? It may be obvious to you, but not to 99% of the people that will run Windows 10.

      The problem is you can't enforce that you're friend didn't enable WiFi Sense without looking over his shoulder. He might end up accidentally distributing YOUR passphrase when he shouldn't be.

      The only way to be sure that this doesn't happen is to add an ugly _optout line at the end of your SSID. Frankly Mr. Joe Person down the street shouldn't have to know about Microsoft's new feature to be confident that his passphrase isn't being passed around without his permission.

    no fucking way. Somebody needs to be fired at Microsoft.

    We all know how to handle this "feature", but most people won't have a clue.

    This is right up there with their leaving file extensions hidden by default.

    However, just because I gave Person A access to my wifi, that doesn't mean I give everyone Person A knows access to my wifi. This could end up in legal hot water territory.

    I guess that I just won't be giving any guests access to my network anymore. They can pony up and get their own mobile data plan for their devices.

    Serious question - who here is not running a guest wifi access point?

    I'm going to guess the vast majority of people running wifi at home. My office has a guest network, my house does not.

    And if you give your wifi credentials to a guest who needs access to your network, they can opt you in without your permission or even your knowledge.

    The only way then to prevent unknown people from having your wifi password is to forbid Windows 10 mobile users from accessing your network.

    That isn't the issue. The issue is YOU being able to share MY WiFi key because I was dumb enough to let a Windows 10 user on my WiFi network. This is akin to me giving you the keys to my house so you can housesit, and you getting a hundred copies cut and distributing them to a bunch of people you know.

    How often do your friends immediately email the Wi-Fi password you just gave them to their entire contact list? The correct answer (unless you have really shitty friends) is never. Now all of your friends will do this by default, unless they are technically literate enough to disable the option. (And even if your friends are literate enough, your roommate/boyfriend/girlfriend/spouse's friends won't be.) It's very aggravating that Microsoft has chosen to so promiscuously share the secrets its users have entrusted to the OS. A Wi-Fi password that might have previously been shared with a handful of friends is now automatically spread to a network of hundreds, and exposed to possible interception by enterprise, underground, and state-sponsored hackers. One really has to question the legality of this feature, unless the wording is very clear and the user opts-in every time.
