We are setting up a web app which serves as a wi-fi hotspot using coova chilli and the Javascript Facebook SDK.
The app has a "login with facebook" button that, once clicked, calls the FB.login() function, which opens a pop-up window where the user can insert his credentials and log in.
This solution is working correctly in desktop browsers but it's not working in mobile devices.
These are the problems I encountered:
Android device - When I connect to the wifi network, the system prompts a notification who says "Sign in to wifi network". Once clicked, the captive page opens up correctly. But when I click the fb login button, I am redirected to the url "http://m.facebook.com/v2.8/auth ..." which is correct, but then the windows freezes and I can see only a wsod.
IOS device - same as before, the cna triggers, the redirect to the fb login page works, but once I insert my credentials, the only thing I can see is a wsod.
Both issues can be bypassed by including apple.com, google.com and other domains used for auth in the hotspot walled garden, and then the user can log in to the network by using the device's browser - Safari or Chrome, it works - as pointed out in this discussion Facebook login on Apple CNA.
The thing is, we want to make it work on the "normal" workflow, that is, to make the app work correctly within the IOS captive network assistant and the Android "sign in to wi fi" functionality.
Do you have any idea how can we solve this? We searched far and wide without any success. Thank you.
EDIT
Solved by using PHP SDK instead of javascript. By generating a login link as explained here. This works also on mobile captive portal assistants such as ios and android ones because the fb login page is opened in the same window and not in popup/iframe. I hope this helps others that may encounter the same problem.

I am pretty sure that I successfully connected to Whatsapp Web from a mobile browser an year or two back. I opened the site www.web.whatsapp.com, the usual desktop interface showed up, and I scanned the QR code using a whatsapp account on another phone, and I was logged in from the mobile browser just as I'd be from a desktop browser.
When I try it these days, as of 2020, it doesn't happen. The url www.web.whatsapp.com is automatically and invariably redirected to www.whatsapp.com.
Did they purposely block this avenue, or is it something to do with my devices?
Was this feature undesirable to Whatsapp in any way?
You have to tell your browser to open it as a desktop site.
On iPhone: click on Aa letters in the browser and click "Request Desktop Website".
On Android: click on three dots in the URL section and check "Desktop site".
I asked a question earlier about if it was possible to use Firebase in a Windows 8/WinJS app. #MichaelLehenbauer told me that I just needed to add the following line to my code in order to fix a bug in firebase.js:
Firebase.INTERNAL.forceWebSockets()
This worked great and allowed me to read and write to my Firebase. However, now I am trying to get auth working in Windows 8 and running into many issues. I am trying to use the Facebook login but when I call auth.login("facebook"), my app loses focus and a new tab in the modern Internet Explorer app (not the desktop app) is opened with the typical Facebook login prompt. If I put in my credentials and hit login, nothing happens. I need to go back to my app but then it fires up a new IE tab and the process starts again. Instead of opening a new IE tab, Firebase should internally be opening an in-app dialog like seen in the top image here.
So, since I couldn't get the Firebase Facebook login working in WinJS, I tried doing the Facebook login myself and then create Firebase users using the email/password auth. However, when I run:
auth.login("password", {
email: "me#example.com",
password: "password"
});
I get the following warning (which is the same warning I received from firebase.js befoore Michael suggested to me to force web sockets):
APPHOST9601: Can’t load <https://auth.firebase.com/auth/firebase?&firebase=[my_firebase]&transport=jsonp&email=me%40example.com&password=password&callback=FirebaseSimpleLogin._callbacks._firebaseXDR13889674277557>. An app can’t load remote web content in the local context.
I'm not sure if this is another web sockets issue or not, but it looks like FirebaseSimpleLogin is just not working very well in Windows 8 apps. Are there any workarounds to these problems? Even better, is there any plan to provide full support out of the box with Windows 8?
Windows 8 is now supported out of the box with Firebase Simple Login.
We are developing a web application in asp.net and HTML5 (+ offline feature) and we are using “Add to desktop” button to create the desktop application.
Before access main screen, we have a windows authentication screen, so people can connect using their domain credentials.
In safari, we have almost no problem. It's the expected behavior when we are online. For the offline mode, safari needs to keep an active tab with the website loaded to allow offline access to it, otherwise safari does not find website – even if it’s cached with cache manifest...
In the desktop application (using “Add to desktop” button), the authentication popup on the main page does not appears. When I trace the HTTP requests, I can see 2 requests with a return status of 401. When I look into the logs, safari sandbox throw an exception (twice tries then abort operation)... The screen remains blank.
any ideas anyone or any fix is planned to correct this problem ?
Thanks in advance for any advices.
It's a problem with iOS 7. Windows Authentication only works in "Private Mode" or in another browser such as Chrome or Puffin. However, there isn't a workaround currently available to save an app to the home screen. Here's a thread on the Apple forums about this same issue:
https://discussions.apple.com/thread/5327078?start=60&tstart=0
The new iOS 7.03 fixes this issue.
I use the latest Facebook SDK in my iOS app.
It uses single sign on, so even after calling Facebook logout method, when user log in again, dialog window saying he is already logged in fine.
In other iOS applications there is a logout button on Safari web view, so user can simply log out from app.
My question is how I can implement such webView in my application?
I know that I can use FBDialog instead of Safari window to control logout process but I need to have possibility to logout exactly from Safari web view. May be the window with logout button is accessible only in the old versions of SDK?
I am also facing this problem,There is no default method to logout from facebook on safari when the app is under development,may be safari will show logout button when your app goes live on app store
I have a web site, that uses facebook to login.
I would like iOS user of safari, to be able to login into this site. You understand i'm NOT talking about a native iOS app..... just a web site visit.
Currently, user can't login from iOS safari, as they can from any desktop environement.
Either login link is inactive, or there is an error message instead of the login popup.
So what should I implement on website to have facebook login work on iOS browser ?
