    With the developer beta of iOS 11 out in the wild, new features of the operating system have been coming to light throughout the week, including an unobtrusive volume indicator and new AirPods controls. In iOS 11, users will also be able to easily join a Wi-Fi network thanks to a new password sharing process between trusted devices, which should reduce the hassle of joining new networks.

    The feature allows one iOS device with knowledge of a Wi-Fi network's password to grant access to a separate iOS device that still needs the password in question. 9to5Mac detailed an example where an iPad was already on a Wi-Fi network, while an iPhone still required the Wi-Fi password to connect.

    All devices must be running iOS 11, and it appears that macOS High Sierra will support the feature as well.

    After navigating to Settings > Wi-Fi and choosing the right network, the iPhone user is greeted with the traditional password screen (seen above), but on iOS 11 when the iPhone is brought near the iPad, a card on the iPad notifies its user that the iPhone wants to join the network (seen below).

    The iPad user can then tap and send their password to the iPhone, which recognizes the password, fills out the information, and connect to the Wi-Fi. As Apple notes, the iOS device or Mac with knowledge of the network's password must be unlocked for the transfer process to work.

    There are plenty more iOS 11 tidbits to discover in the wake of the official unveiling this week at WWDC, so be sure to check out the MacRumors iOS 11 roundup to find out everything we know about the newest version of iOS.

    What about corporate situations where we don't want our end users having or knowing the password? Is there any way as an IT administrator to disable this for our network?

    Corporate wifi should be using radius type authentication not PSK.

    I hope this doesn't allow someone who received the password via sharing to then share that password with others; otherwise it seems like it could lead to an explosion of new Wi-Fi clients when you only meant to let one on your network. :)

    I hope you're using RADIUS (username and password, or "enterprise") authentication, which I doubt this iOS feature supports--or at least I hope it doesn't, but I guess maybe it would be nice if someone could confirm. If you're just using one password (pre-shared key/PSK), I don't see how this could be disabled on a per-network level except perhaps on corporate-owned devices, where Configurator or Casper/JSS might be able prevent such devices from being the "sharer" (but that won't help other devices).

    This is one my favourite little things in iOS 11.

    Android and Windows Phone have\had methods of streamlining WiFi password sharing too. But none I've used have been this slick.

    How would that be any different than verbally telling someone the password? They could then verbally tell someone else...

    Unless you're thinking of a different scenario where people are now being granted access under the new system, where they wouldn't have been given the password under the old...

    If someone wants access to your network, you don’t have to tell them the password. You can ask for their device and type the password in yourself. Then they have access to the network but don’t know your password. This seems to bypass that bit of security as now anyone with access to your network could theoretically grant access to additional people.

    That said, if you’re that concerned with securing your network, either properly vet those you grant access to, use a different authenticion method, guest network, etc.

    No thanks,the people that need my wifi password already know it. What's wrong with just write it on a piece of paper,or type it on their devices myself,as I usually do? I don't want my password spread to whoever want it.

    This is not secure at all. For example, if the person has activated iCloud Keychain, the Wifi password may be synced to a Mac where it can simply be viewed in Keychain Access.
    Yup.

    Either you let the device store the password in the keychain or you have to enter the password every time the device is re-joining your network (eg, when people come to work in the morning). And if the password is stored in the keychain, the user can just look it up via the Keychain Access app.

    apparently you can see the password in keychain on a Mac, so typing it in yourself might not be as secure as you think.

    I think this is a great feature for the typical home network. I'm guessing there will be a way to turn it off if you don't want it.

    I think in iOS 11, you can even get access to the password stored in the local keychain (you can already do so for passwords stored 'by' mobile Safari).

    There you go. So it boils down to this not opening any security holes. It just removes some obfuscation. And security through obscurity is not security at all. If you don’t trust the person you’re granting access to, then you shouldn’t be granting access to them.

    As this is a device-level feature and not a router-level feature, I don’t think that “turning it off” would offer any security benefits. That would just prevent you from sharing the password, not others who have been granted access.

    Bottom line is wifi security via a password alone is not secure.

    After everyone realizes they will lose all their 32 bit free & other games, they will realize that IOS 11 is as Steve Jobs once said, "A Bag of Hurt."

    Another reason to only allow network access to specific MAC addresses and deny all other devices which attempt to access the network. Of course, that approach requires that the person trying to gain access to the network isn't savvy about spoofing MAC addresses.

    Does it actually show the password to the user, or does it just fill it in with dots and connect them?

    LOL, really, You can pay for Cisco ISE then. the rest of us with real budget constraints will use Hidden SSID's and complex Passwords. Guess you never heard of Intermec Scanners and Other Items like that.

    For certain situations I see this a great feature. For other situations not useful.

    I am no expert, so forgive the question. Does this pose a risk any greater than responding with a password when logging on to the WiFi system?

    This is going to be very useful! The WIFI password to our network is long and not very memorable.

    Now if only my phone would share my WiFi password with the Airport Utility app that's on my phone. That would make re-starting the Airport easier, and reduce the quantity and volume of my curses.

    For some reason, I am reminded of the old Samsung advertisements which showed one person sharing a video with another person by holding their phones next to each other...

    How about they actually make "Forget this Network?" last permanently, like it should? :D
