Qlik Sense Mobile supports and leverages whatever authentication mechanisms are configured on the Virtual Proxy in Qlik Sense Enterprise. It's actually the Qlik Sense Hub which authenticates the Qlik Sense Mobile users! Engage a Qlik Consultant for assistance with this, but you're looking at a custom Ticketing authentication solution for Qlik Sense, or *simpler* put a SAML 2.0 front-end on your database, and configure SAML authentication in Qlik Sense!
