I have a login page in my Ionic App. The current behavior of the app is as below:
After downloading the app, User launches it.
The app shows Login Options (buttons) page (right now, I only have Microsoft (Azure Active Directory)).
Tapping any of the options, the app asks for login credentials (email and password).
The app authenticates these credentials against the server/corresponding vendors.
Upon successful authentication, the user is taken to Home Page of the app.
Now the important part, for all the subsequent launches, when the user taps on the 'Microsoft' (again, this is the only option I have right now) button it doesn't ask for credentials (emails ID and password). Instead it takes the User to Home Page directly.
So, I am sure the user credentials and/or its corresponding token or something similar is being maintained in the device somewhere.
How do I access this information programmatically?
What I am trying to achieve is: If the user credentials/token already exist on the device then don't even shot the Login Options Page. Take the user to the Home Page directly after the app is launched.
Any ideas/pointers/suggestions on how this can be done.
Thank you!

I was playing with inspect element the other day and what I did was I opened facebook in two tabs and logged out from the other tab. As soon as I returned back to the logged in tab, it showed me Login modal. How did it check instantly as no service request was made to allow them to check if the user has logged out.
Same happens with manual cookie clearance from Application tab in the developers console and also if you deactivate your account from app, the website open on your laptop shows to login. How does that happen so instantly? Is that a Websocket?
I was able to successfully login to Facebook and get required permissions for my Windows Phone 8 application using the tutorial here -
http://facebooksdk.net/docs/phone/controls/login-ui-control/
Now, the login button control opens up a browser window and asks the user to login.
Then the user logins and grants permissions to my app.
Then the user is redirected back to my app on the phone and sees the login button changed to logout button.
When the user will click on the logout button, the session data is removed from the loginbutton control. So my app sees the user as logged out.
But when the user logs in again, he is not asked for his credentials and is directly logged in to his account - this is because the user actually never logged out of the web browser window in the Windows Phone application.
So how do I logout the user from the browser control in my Windows Phone 8 application.
All help is greatly appreciated!
The user is not asked for his credentials because the Facebook authentication cookie is still present in the WebBrowser control.
So to completely logout the user from Facebook, you need to clear the WebBrowser cookies.
Unfortunately, there is no easy way for erasing cookies on Windows Phone 7.
On Windows Phone 8 you just need to call ClearCookiesAsync:
await new WebBrowser().ClearCookiesAsync();
Here is a tutorial that makes use of it: http://www.developer.nokia.com/Community/Wiki/Integrate_Facebook_to_Your_Windows_Phone_Application
When a user is not logged in and they navigate to a page tab made with our app, they get an obtrusive dialog asking them to log in:
This has nothing to do with http vs https, the app is not in sandbox mode, there is nothing in the tab asking for a login or user information, etc. I've gone through the app settings at least a half dozen times now, and nothing is wrong there. Aside of urls, the settings are identical to another app I have that does not suffer from this problem. I'm stumped!
Edit: here is an affected tab: https://www.facebook.com/StaticHtmlThunderpenny/app_203351739677351
This message is not about login to your app, but Facebook in general.
So my guess would be that the page your app is installed as page tab app on is restricted in some way – by age, location, or for having alcohol-related content. And then of course Facebook asks for login, because otherwise they can not determine whether or not the (as of now still “anonymous”) user qualifies to see the page.
So go check the page settings.
This is actually not app related question.
This is thumb rule!! To access any app on Facebook, you need to log in to Facebook. You can see Facebook page without log in. But for facebook apps, you should be authentic user.
with this issue in my own experience that I came across some years back with a facebook app that I was running, if this doesn't relate to any of your other social networking apps then am aligning two set of possibilities and solution.
The user might have not properly logged out as "written" in the app for the users logout stage.
Solution would be that the user logout as expected before closing the app.
The user might have set up an automatic login prompt which was removed by the app when it was been updated automatically. (If you do get me???)
Solution would be to monitise your app on updates and login informations or better still just login and logout ask intended by the app and for security reasons.
Lastly I would say that automatic bookmark database should be added to the server part so current pages as the user uses the app would be saved after logout or login stage. Thank you, hope this helps and if not let me know what am missing.
I have installed the facebook API in phonegap but i have hard time making it work see link .The index.html file in the exemple folder has a login button that once taped opens the native facebook application on my device requiring email and password. After having authenticated me, it takes me back succesfully to my app.
Whenever i tap on the "getsession" button for exemple it shows me an alert saying "undefined". I want to know how to get the access token that is given right after the authentication process within my app and everything related to the session so i can perform other tasks?
Thank you
When the person opens my app, I want to display a button. The user clicks this button, and it opens a browser (embedded, of course) inside the app, allowing the user to LOGIN through that web page.
Of course, when the person logs in, it only logs in to that web server. The web service now knows that the user is logged in.
As the user uses my mobile app, I need to know if he's logged in or not. How can I know? There's no way for my app to determine if the user is logged into my web service.
By the way, I am using Django framework for my web service.
Well, presumably when your user logs in the server is telling their browser to set a cookie. Why not just capture this cookie and use it to determine if they successfully logged in?
