Hi, we are having issues again with Facebook login. It keeps showing the Facebook login screen suggesting that you install the Facebook app... However, this is already on the device.

Now I tried to find info on this as it seems to affect a lot of mobile users (seems only iPhone), and I found this: stackoverflow.com/questions/32566734/nat...ebook-login-in-ios-9

That is exactly what we are experiencing. App is already on device, why is user required to enter username and password every time to log into Facebook to then log into our site...?

I have no idea. How are you instructing the phone to load the app in the first place? That's not a feature of JFBConnect, so I'm unsure of what you're doing or how it's working.

The only suggestion I can give is to disable auto-login in the Facebook area, if it's enabled. That's the only setting I'd think would be trying to log the user in from JFBConnect.

If that doesn't help, please describe a bit more and we'll gladly help however we can.

Thanks,
Alex

Hi Alex... See attached screenshot from mobile. That is what we get all the time although Facebook app is installed and configured on mobile... Why does the user need to always login, I though that having the FB App and this FB login would make it simple and so user do not have to everytime enter username and password...

Ahh.. I understand. I thought you were saying you had your own app for the site.

Unfortunately, the Facebook App doesn't work that way. Apps have restrictions and they can't really cross communicate with other apps, like Safari. There's no way for Safari, and specifically your website, to know if the user has the app installed and if they are logged into it. I've never heard of the app working like that, but if you have an example of a site that does log you in based on the Facebook App or, even better, documentation from Facebook explaining how that would work, I'd gladly investigate further.

Thanks,
Alex

Alex, has this changed then? As it was different. Previously you would log in once via facebook popup on mobile and then it would remember you when you clicked 'log in with facebook'. This was on mobile.... It was great as users did not have to remember their fb login all the time...

This link has a discussion about it: stackoverflow.com/questions/32566734/nat...ebook-login-in-ios-9

That discussion is about using your own custom apps, not about logging in from the website using Safari. Just to make sure, you're not using your own custom iOS app (like from the App Store), correct?

If so, to my knowledge, nothing has changed. However, Safari is continuously being more locked down with each release for security and privacy. My only guess is that cookies or other session data is being destroyed as you close and open the browser.

Can you test going to Facebook.com *in safari* and authenticating. Then, go to your app to see if the login process puts up the authentication prompt? Again, this is all outside the Facebook App (from the app store).

Thanks,
Alex
