Two years after sharing Netflix's initial passkey deployment journey at Identiverse 2024, we return with a deep dive into the challenges and triumphs in achieving true enterprise-wide adoption. As both our business and phishing resistant technologies have evolved, we encountered complex edge cases that tested the limits of true passwordless authentication. 

This session will share practical insights and data from scaling passkey implementation across a diverse (and sometimes hesitant) user base, navigating changing technology ecosystems, and managing inconsistent platform experiences. Through real-world examples and hard lessons learned, we'll explore practical strategies for tackling the "last mile" of passkey adoption and the realities of maintaining security and usability in an evolving business landscape– and share how Netflix's culture with an (almost) no rules rule shaped our approach to achieving comprehensive phishing resistance in a diverse environment.
