1. SecurityEventsService: Centralized audit logging for all auth events
(login, register, logout, password changes, API key operations, SSO
token exchange, etc.). Fire-and-forget pattern ensures auth flows
are never blocked by logging failures.
2. AccountLockoutService: Locks accounts after 5 failed login attempts
within 15 minutes. 30-minute lockout duration. Fails open on DB
errors. Clears attempts on successful login. Email-not-verified
does not count as a failed attempt.
3. API Key validation endpoint secured with rate limiting (10 req/min
per IP via ThrottlerGuard) and audit logging. Key prefixes logged
for forensics, never full keys.
New schema: auth.login_attempts table for tracking failed logins.
174 tests passing across all auth and security modules.
