Authentication Flow Scanner

Test your login, signup, and password reset flows for common security weaknesses.

Authentication is the gateway to your application. Our scanner tests login forms, signup flows, and password reset mechanisms for common vulnerabilities including weak password policies, account enumeration, brute force susceptibility, and insecure password reset tokens.

What This Scanner Does

Tests login endpoints for account enumeration through error message differences, checks password policy enforcement, analyzes password reset flows for token security, and verifies rate limiting on authentication endpoints.

Why It Matters

Broken authentication is consistently in the OWASP Top 10. Weak authentication allows account takeover, credential stuffing, and unauthorized access. Even a single flaw in your auth flow can compromise all user accounts.

Common Findings

  • Different error messages for valid vs invalid usernames
  • No rate limiting on login attempts
  • Password reset tokens with insufficient entropy
  • Missing multi-factor authentication option
