I'm using HybridAuth with Laravel. How can I allow the user to choose a (different) Facebook account after logging out of my UI?
Currently, when the user logs out then in, it auto logs them into my site because they have received a token previously. They are not given an option to log into a Facebook account. Therefore, the user can only use one Facebook account with my site, ever. I tried deleting session data as well as $hybridAuth->logoutAllProviders(); and it still happens.
I could set the Force Web OAuth Reauthentication setting in Facebook for my app, but I don't want the user to log into Facebook every time they visit my site. I would like them to be able to switch Facebook accounts they want to use with my site.
I get expected behavior when logging as a Google user. Thanks for any advice!

I can connect to facebook and check on my users and link their account with their facebook profile. But I a question about logic.
When the user comes back to my site, and then want to login again (using facebook), do they have to also be logged in to facebook at that point?
I am using the PHP SDK
If they are logged in before they get to your site, the users will directly see contents allowed to authenticated users. The identification information can be stored by the client's browser (cookies, cache, session...) for automatic log in.
Whenever a user is connected through fb services within a session, his credentials are the same on all websites using fb services within this session.
Hope it helps.
I have a website where users can log in with the Facebook oAuth API.
Once the user logs in or registers via Facebook it is stored in my database.
But what I'd like to achieve is, once the user goes to his Facebook application settings page and removes my website app permissions, the used should also be deleted from my database.
Is there any work around to this problem, if this is not possible via the Facebook oAuth API?
You can add Deauthorise Callback URL by Navigating to Settings > Advanced section of your application. Whenever a User Deauthorises your Facebook app, Facebook performs a HTTP POST of signed request to your URL. You may use the field user_id to determine which User has deauthorised your app.
Actually, I would do the following:
Add a date to his last log in to your site.
Have cron job check for old, unused accounts.
Send an email to the user's email address (or Facebook message mail) telling him his account is due to expire soon.
Delete account from database.
Well i want to allow Facebook login on my site. I have created the API and user's can login to the website. But for the first time a pop up comes to the users asking for Permission.

Can i just skip the users from this permission page and directly logs them in.
Thanks
Any person must accept the basic permission for getting their Facebook profile data for use in your website
I'm trying to write application for user login to website via Facebook. When user is logging in, he's redirected to http://www.facebook.com/dialog/oauth/?client_id=APP_ID&redirect_uri=REDIRECT_URL&state=STATE, then sees confirmation dialog to use permissions and all goes well. But then FB somehow remembers this application and never asks for permissions confirmation again when user opens this url. Is there any way to always show this dialog? I could do it in Twitter, but couldn't found the answer for Facebook.
If you really want this for some reason, uninstall the app from the user's account with a HTTP DELETE request to /USER_ID/permissions using your app access token.
The next time they come back they'll need to re-authorise the app.
Otherwise, no, there's no way that I'm aware of apart from the reauthentication flow to force the auth dialog to appear, but bear in mind that the reauthentication flow may prompt the user to re-enter their Facebook password even if they're already logged into Facebook, so it adds extra friction to the process
Instead of showing the Facebook OAuth dialog, you could also show the user a page on your application that has some information about the Facebook account that is going to be used (picture/name etc), to log into it. That way, if they like they can choose to log out and re-authenticate or continue knowing they have the right account.
well i have used the facebook api couple of times. But last day i just came across a site which was really new to me. Heres the scenario
If a user is logged in at facebook and comes to my site, he will
automatically be logged in without asking him and also if user logs
out of my site he gets logged out of facebook. But the site i saw
yesterday, they had handled it perfectly, user dose not logs in their
site automatically and even if user logs out from their site, he does
not gets logged out of facebook.
So any help? what is this technique called? or any relevant help?
Best Regards
most site handled the login/authenication by using the login status of the user at facebook ends.
to do what u wants, simply add an additional layer of authentication / login status checking at your own site.
The site level login status is to be retained only for the current session. In other words, once the user went away from the site, the site level login status is gone. With this, when the user returns, you know that he needs to login again.
when the user logged out from your site, you only log him out of your site and do nothing about facebook login
Using the Facebook SDK it will likely tell you the user is logged out when not logged into Facebook, which in theory is the correct behaviour of the whole system, as Facebook want user's to always be connected to Facebook, I quote facebook:
As long as the user is signed into Facebook, they are automatically signed into your site as well.
So if they aren't connected to Facebook, you aren't connected to other sites. In a way it's a deterrant and increases Facebooks market.
But anyhow, it's likely the site you are describing are implementing their own authentican system rather than using Facebook's own SDK, or if they are using the SDK they are using it in moderation and understand about cookies/the above.
The flow to allow the user to be logged into Facebook but out of your site is as so:
When a user logs out of their site, it will unset session data for the site's own application, and also unset Facebook cookies, etc. That way the user is still logged into Facebook but out of your site.
When they try to log in again, Facebook will detect no cookies are available and hence will re-authenticate and pass you onto the url as passed during the authentication process. Your site will then login the user to the site's own application, setting any session variables, etc.
you need to check how you are handling the FB logins and sessions at your end..
my guess is you check the is login at your site and there are some access_tokens which are as per your app id in the cookies of your browser which are helping you to log in ..
and when logging out from your site you are explicitly logging out the user from FB as well
( thats what you are describing atleast )
you seem to be explicitly calling logout or clearing the cookies for fb app id ..
