How KAYAK reduced sign in time by 50% and improved security with passkeys

KAYAK, a prominent travel search engine, has integrated passkeys into its Android and web apps to enhance security and streamline user authentication, reducing sign-up and sign-in times by 50%. This move away from traditional passwords addresses vulnerabilities such as phishing and hacking, and decreases user friction seen with previous methods like magic links. By using the Credential Manager API, KAYAK unifies passkey support and traditional sign-in methods within a single interface, simplifying the authentication process. The implementation of passkeys has not only improved user satisfaction by eliminating the need for complex passwords but also reduced technical debt by consolidating various authentication methods into a modern user interface. Thanks to these advancements, KAYAK plans to phase out password-based authentication by the end of 2023, showcasing a successful model for securing and enhancing user experiences in mobile applications.
