Can I authenticate for Facebook login via the app?

Problem

While logging in to the WiFi network using the Facebook widget users must enter the credentials. Because of that, the login is not "click through", even though they're already logged in on the Facebook mobile app.

Explanation

The captive portal pop-up is a completely separate thing from the Facebook app and a traditional browser. This makes it impossible to have credentials from the app or browser stored inside the pop-up window. The issue affects only some mobile devices, as they don't share cross app data in such cases.

Solution

Some of the devices (such as Apple iPhone) provide the option to store the credentials inside the device. You can save the credentials in the mobile device memory (Options -> Passwords for Apple devices), and "reuse" them in the pop-up window such as our Captive Portal solution.
