Passwordless Authentication: WebAuthn and the Future of Logins

WebAuthn enables strong, phishing-resistant authentication using public-key cryptography and platform authenticators (e.g., biometrics, security keys). It’s a core part of passwordless strategies.

How it works

1. Registration: client generates a key pair, public key stored with server
2. Authentication: server challenges client, client signs with private key

Benefits

• Phishing-resistant
• Better UX (no passwords)
• Reduces credential stuffing risks
