Really excellent breakdown of IAM fundamentals here! Your explanation of passwordless authentication really clarifies how it fits into the broaderMFA landscape rather than replacing it entirely. The distinction you make between authentication factors (something you know, have, are) and the session management lifecycle afterward is crucial but often overlooked in practice. I've seen too many organizatoins implement strong MFA at login but then leave sessions open indefinitely, creating a massive gap in thier security posture.
Appreciate the comment. Passwordless auth certainly removes user friction and is a form of MFA, just without the "something you know" factor, but it adds "something you have" (a physical device) and "something you are" (biometrics). That said, traditional MFA will continue to live (at least for now) because it's widely supported and easier to integrate with existing infra.
