Is it possible to use the application from FaceBook when authorizing (registering) on ​​the site via FaceBook, on a mobile device?

Question

Facebook

I have a website that implements authorization through social networks, including FaceBook (hereinafter referred to as FB). If the user is already logged in to FB, then when trying to log in to the site through FB, he does not need to enter FB data, but simply give permission to the requested rights (mail, profile, etc).
Actually the problem is the following. On mobile devices, I think the vast majority of users visit FB using an app, not a browser. And when they try to log in to my site in the browser, they are redirected to the FB page, where they must enter their data to enter FB, although in the application on the same mobile device they are already logged into FB. The question is whether it is possible to use the application for login via FB from the browser.

Answer 1

No, this functionality is only available for Android/iOS apps using the Facebook SDK.

Answer 2

Has anything changed in this regard? Can I now use a user account in the FB app on a mobile device to log into my website?
