iPhone showing Personal Hotspot password to the public

edited August 14 in Other

Looking for a reality check here. Maybe I'm extremely paranoid about security and privacy (though I think I'm not).

So, the iPhone's "Personal Hotspot" settings page has to be opened and kept open for you to be able to connect your other device(s) to the Personal Hotspot.

And it is showing the Wi-Fi password in the clear, for everyone in the café to see, all the time, without any way to turn this off!

Is this just me being paranoid or is this a bafflingly huge security hole?

I've DuckDuckGoed it and noone seems to take issue with it.

Am I crazy?

(N.B.: I'm on iOS 14.2, maybe this has been fixed since then.)

    Are you serious? Turn off your "Allow Others To Join" slider button.

    😄

  • “Or when you turn it on in control center”

    Try that to obscure the password.

  • @SevenSystems : that page doesn’t have to be open to use your hotspot. I am not sure what gives you the impression it needs to be left open to use it.

    Exactly - it doesn’t need to be open. Nothing to see here, carry on @SevenSystems. Plenty of things to be pissed at Apple about, this is not one. 🤨😛

    Oof, OK. Yeah I somehow had the impression that the network was only visible while that page was open. It also is slightly implied in the explanatory text ("when you are in Personal Hotspot settings"), but I guess it's enough if it's turned on, no matter how.

    Sorry, I'm an idiot 😄

    Meanwhile, we now know you are in a cafe in Ireland somewhere, fuming over you cappuccino while staring at DuckDuckGo on your iPhone 12, some other device on the table…cameras scanning, ok, found. Sending the lads in now 🤣

    Yep. Mea culpa. I'm not sure why I remembered this to be the case... maybe it was in earlier iOS versions. Good stuff though, I can finally stop leaving my poor phone's display on all day while in the office 😂

    I KNEW the two conspicuously (SP?) whispering ladys at the next table had received secret Gavinski instructions 😜

    Hey, just cos you're paranoid doesn't mean... 😂

  • :)) as with all things, i think there may be a little right on both sides?

    i too use a hotspot ,, and have found i need to keep it open on that very screen

    why? if i drop connection,,, which happens,,, i need to reopen the phone back to that screen, and go again...

    hence,, i leave it open on that screen,,,

    That would be an ecumenical matter, though, surely?

  • Just confirmed: The Wi-Fi network disappears after some time when the phone is locked (iOS 14.2). So maybe I do remember correctly.

    i.e.:

    1) Go to the "Personal Hotspot" settings page
    2) Connect to the Hotspot using a computer
    3) Lock phone. Computer stays connected
    3) Reboot computer
    4) Computer doesn't see Personal Hotspot anymore

    Oh well, first world problems I guess...

  • I guess the hotspot is turned off to save battery if nothing is connected to it ? Maybe an automation/shortcut trick can keep the hotspot alive ? 🤔

  • @Etienne said:

    Maybe. But I feel at least 50% confirmed in my initial "complaint" about the security aspect of this.

    Many Personal Hotspot users will probably feel the same and intuitively think that they need to keep this page open for the Hotspot to work, thus exposing their password to anyone walking by. I still think it's bad design.

    You can turn access on and off on from Control Center. Long-press on the tile with the network widgets to access the hotspot switch—which does not reveal the password.

    Yes, this is actually the perfect solution, thanks. Left the "extended network tile" open with phone unlocked for a couple of hours and all devices could repeatedly connect. Thanks!

    A bit odd that Personal Hotspot cannot be added to Control Center directly (i.e. to the first level) 🤔 (at least on my ancient iOS)

  • I'm wondering if laying the iPhone down on its screen would be a good solution? 🫠 The screen will remain open, but nobody can see it then, unless it's a glass table. 😂 And I'm sure nobody would put their face by your crotch to look up at your phone's screen. (Sorry, but I'm high, and this thread has me cackling.)

    Bah. That's nothing a little duct tape can't correct. If you're the type of person who would venture out to Starbucks without a roll, then you deserve to have your password compromised.

  • @SevenSystems said:

    Haha. I'm curious though, what way do you think it should be done? You never need to look at the page with the password except if you need to see the password. You do need to know the password when connecting a device for the first time, so it must be possible to see the password. If you don't need the password you just connect via the hotpot icon rather than opening that page with the password on it. I guess they could add a show/hide password toggle to the page you screenshotted, but given there is the option of connecting via icon, and you can easily close or move away from the page with the password, is it really needed?

    I wasn't aware that you could activate Personal Hotspot through tapping and holding on a group of Control Center widgets. I'm assuming 90% of people don't. Maybe more.

    The way it should've been done is to simply hide the password with dots, with an "eye" toggle to show it, as in other places. Also, it should be made clearer how to access Personal Hotspot via Control Center. Currently, the text says "or when you turn it on in Control Center". This made me believe that it would be possible to add a button for it in Control Center, which is not the case. Only possible via tap and hold. So the text should be rephrased as "or when you turn it on by tapping and holding on the network toggles in Control Center" or something.

    Yes everyone here seems to think I'm too picky, but believe me -- this stuff matters!
