DESCRIPTION:This presentation explores a novel approach to passwordless aut
 hentication in Gnome\, leveraging the power of [SSSD](https://sssd.io/) an
 d a newly developed extension to the Pluggable Authentication Module (PAM)
  conversation. We introduce a JSON-based messaging system that significant
 ly enriches the communication between PAM modules and client applications\
 , enabling sophisticated authentication flows. This enhanced communication
  facilitates contextual information sharing\, adaptive authentication\, an
 d seamless multi-factor authentication\, all within the familiar GNOME des
 ktop environment.\nThe talk delves into the technical details of this JSON
 -based interface between SSSD and [GDM](https://en.wikipedia.org/wiki/GNOM
 E_Display_Manager)\, providing insights into its [design](https://github.c
 om/SSSD/sssd.io/pull/79) and implementation. Furthermore\, a simple PAM ru
 st application will be presented as a practical example\, serving as a ref
 erence for developers seeking to integrate this protocol into their own PA
 M applications. This opens up a wide range of possibilities for enhanced a
 uthentication flows\, including:\n\n* **Contextual information**: sharing 
 user-specific data or authentication challenges.\n* **Adaptive authenticat
 ion**: dynamically adjusting authentication steps.\n* **Multi-Factor authe
 ntication**: orchestrating complex authentication sequences.\n\nThe presen
 tation will conclude with live demonstrations showcasing the capabilities 
 of this extended PAM conversation and its potential for innovation in auth
 entication systems.\nWe will also share the current development status and
  preliminary GUI designs\, subject to ongoing development progress.
