The discussion centers around the effectiveness and practicality of adopting passkeys as a replacement for traditional passwords. Critics argue that passkeys do not fundamentally differ from password managers, as both require a form of trusted device to access accounts. While some commenters express enthusiasm for a future without passwords, concerns abound regarding compatibility with various accounts, ease of use compared to SSH keys, and security risks associated with lost or stolen devices. Overall, there is a call for broader implementation and better management solutions for passkeys across different platforms.
