Section Access implementation in Qlik Sense differs from QlikView. In Qlik Sense, there is no local app login. Everything is tied to the authentication to the Qlik Sense server.
Please review the documentation here:http://help.qlik.com/en-US/sense/2.2/Subsystems/Hub/Content/Scripting/Security/manage-security-with-section-access.htm?q=section%20access
Notice that the concepts of USERID has changed from QlikView to Qlik Sense and there is no PASSWORD field in Qlik Sense section access. These elements made the local login process possible with QlikView. Like I said, Section Access is different from QlikView to Qlik Sense because it is tied to the overarching security model from an auth standpoint.
