For two decades, I have witnessed firsthand the systemic failure of the shared secret model, the password. It is not merely a user convenience issue; it is the single greatest architectural liability in global Identity and Access Management systems. Passwords violate the core tenets of modern security by relying on fallible human memory and introducing static, reusable credentials vulnerable to mass exploitation like credential stuffing and sophisticated phishing campaigns.
As the industry shifts toward Zero Trust, relying on passwords is an unacceptable and costly risk. This paper presents an expert assessment, confirming that passwordless authentication is the nonnegotiable mandate for contemporary IAM. By adopting cryptographically sound standards like FIDO, organizations shift the security perimeter from a memorized secret to a hardware-bound, unique key. This approach achieves a superior risk posture, enforces real-time policy context, and dramatically reduces the operational drag created by legacy credential management. The adoption of passwordless technology is now a strategic necessity for business resilience and regulatory compliance.
