The Verification Step Is the New ATO Battleground in 2026

This contributed article argues that mainstream adoption of passkeys and passwordless authentication is pushing attackers away from credential stuffing toward exploiting identity verification and recovery flows (magic links, re‑enrollment, step‑up flows) and leveraging generative AI for impersonation (deepfakes, synthetic documents); it recommends making passwordless and biometric liveness baseline controls, treating re‑verification as high‑risk, adopting intent binding, and using network‑scale signals and regulatory alignment to reduce ATO risk.
