Software on a router receives configuration data that specifies a social networking service as a source for authentication according to an authentication protocol. Subsequently, the router software receives packet data from a client device for a destination other than the social networking service. The router software causes software on the client device to display a login view for the social networking service. The router software transmits the login data entered in the login view to the social networking service. And the router software receives an authorization code following a successful login by a user identified on an access control list (ACL). Then the router software transmits the packet data to the destination.
