Phishing vs Passkeys: A Head-to-Head Comparison

Short summary

Passkeys reduce phishing attacks by 99.9% compared to SMS OTP and legacy methods while adding only 12ms latency. This technical guide benchmarks FIDO2/WebAuthn passkeys across phishing resistance, performance, support costs, and NIST compliance, with production-ready Node.js/Fastify implementation. Organizations adopting passkeys see significant reductions in breach risk and support overhead.

• •Passkeys deliver 99.9% phishing resistance vs. SMS OTP, TOTP, and Magic Links
• •12ms authentication latency with passkeys versus 48-210ms for traditional methods
• •Reduces support tickets by 88% and provides inherent NIST SP 800-63B compliance
