Facebook Authentication 2.0
Facebook authentication allows you to give users access to your Wi-Fi networks using their Facebook credentials. You can request Likes and Shares (wall posts). In addition, you can request or require email address and birthdate.
Facebook Authentication System Profile
Give your authentication system a unique name. Authentication System Name appears in the SputnikNet interface. Display Name is shown to users if you have more than one authentication system in your captive portal.
Optionally set maximum upload and download bandwidth rates (in Kbits/second) for all users logging in through this authentication system. Note that for these limits to be applied, bandwidth limits must also be enabled on the router.
Enable users to log back in automatically within the provided Time Limit, bypassing the need to re-enter Facebook credentials for a limited time. Roaming restricts this to the original router the user logged in on, or to apply to all routers using this authentication system.
Facebook Authentication System Settings
Enter your Custom Facebook App ID and Custom Facebook App Secret.
You can set this up at developers.facebook.com.
Enter any custom text that will be displayed to users during login.
Optionally request or require that users allow you to access their Facebook email or birthdate. Note that if you want to request or require the users' birthdate, your app will need to be reviewed by Facebook. More information is at developers.facebook.com.
Optionally request a Like or Share (wall post) once, a specified number of times, or always. Set the target page to be Liked. Please note that Facebook pages provide a better user experience than plain old web pages. (Surprise.) Please note: changing the URL won't restart the "Like" counter. So if users already liked the prior page, those Likes still count even though a different page would be the target of new Likes.
Set a session time limit if you want to force users to re-login periodically.
Allow User to Skip CRM
You can skip a CRM (survey) for users of the Facebook authentication system always or if they responded to any of the profile data questions.
