web-auth-defenses-testing
Methodology for testing authentication defenses on web apps — login lockout/rate-limit scope determination (global vs per-account vs per-IP), forgot-password error handling, auth-route method/logic anomalies, and hosted-app (Next.js/Vercel) auth probing. Produces correctly-scored findings (Critical vs Medium) and safe, non-destructive testing.

# Web Auth Defenses Testing
## Purpose
Test login/account-defense controls the way a bug-bounty reviewer scores them: determine *scope*
of any lockout, find logic anomalies, and confirm (or refute) hosted-app auth weaknesses —
without locking real users or sustaining an outage.
## When to use
- Target exposes `POST /api/auth/{login,register,forgot-password,mfa/verify}` or similar.
- You see a "too many attempts" / lockout / rate-limit response during auth testing.
- You're assessing a Next.js/Vercel or other hosted-SPA app with separate auth + backend services.
- Companion to `web-pentest` (this skill drills the auth-defense sub-area in depth).
## Phase 1 — Lockout scope determination (MOST IMPORTANT, drives severity)
