Passwordless Authentication

Password management has always been a headache. Remembering complex passwords, dealing with password resets, and securing sensitive data—these tasks can be cumbersome and insecure. Enter passkeys and WebAuthn, the future of passwordless authentication. These technologies promise to simplify user authentication while enhancing security. In this post, I’ll walk you through the challenges, solutions, and practical implementation steps. The Problem: Password Fatigue and Security Risks Traditional password-based systems suffer from several issues: ...
