Authentication Testing

Automated authentication security testing: signup, login, 2FA/OTP bypass, CAPTCHA, bot detection using Playwright.

Quick Start

1. Initialize Playwright
2. Test: signup → login → 2FA → CAPTCHA → bot detection
3. Document findings with evidence

Core Workflows

Account Registration: Navigate → analyze form → generate password (PasswordGenerator) → create account → store credentials (CredentialManager)

Login Security: Test bypasses → credential validation → session tokens → fixation/hijacking

2FA/OTP Bypass: Enable 2FA → test vectors (response manipulation, direct access, parameter removal, code reuse, brute force) → extract OTP from email

CAPTCHA Assessment: Identify type → test server-side validation, token expiration, reusability → bypass vectors

Bot Detection: Stealth mode → human-like behavior (natural mouse, variable typing, random pauses) → test detection

Credential Tools

PasswordGenerator (tools/password_generator.py):

from tools.password_generator import generate_password
password = generate_password(hint_text="8-16 chars, uppercase, lowercase, numbers")

CredentialManager (tools/credential_manager.py):

from tools.credential_manager import CredentialManager
mgr = CredentialManager()
cred_id = mgr.store_credential(target="example.com", username="test", password="pass")
cred = mgr.get_credential("example.com")

See reference/PASSWORD_CREDENTIAL_MANAGEMENT.md.

Playwright Automation

REQUIRED: All browser automation via Playwright MCP.

Human-like: Natural mouse, realistic typing (80-200ms delays), random pauses (500-2000ms), smooth scrolling Evidence: Screenshots before/after, network logs, console output Stealth: Hide webdriver, add chrome object, randomize fingerprints

Testing Techniques

CAPTCHA Bypass (11 techniques - reference/CAPTCHA_BYPASS.md): Missing server validation, empty field, reusable tokens, HTTP header manipulation, content-type conversion, request method, parameter manipulation, OCR, response interception, token expiration, session persistence

2FA Bypass (10 methods - reference/2FA_BYPASS.md): Response manipulation, direct endpoint access, OTP parameter removal, code reusability, brute force, predictable codes, session persistence pre-2FA, backup code abuse, race condition, OTP leakage

Bot Detection Evasion (reference/BOT_DETECTION.md): Behavioral biometrics, fingerprint randomization, User-Agent rotation, WebDriver hiding, natural timing, request patterns

Common Vulnerabilities

Critical: Missing 2FA server validation, reusable OTP, direct access without 2FA, client-side CAPTCHA High: Weak OTP generation, no rate limiting, CAPTCHA token reuse, session persistence pre-2FA Medium: Weak bot detection, account enumeration, timing attacks, info disclosure

Testing Checklist

Pre: Scope, test accounts, Playwright configured, email access During: Signup, login, 2FA, CAPTCHA, bot detection, evidence Post: Findings documented, PoC scripts, CVSS scores, remediation, cleanup

Critical Rules

Always: Test accounts only, document scope, responsible disclosure, clean up Never: Exceed scope, cause disruption, expose findings before remediation

Tools

Playwright MCP, PasswordGenerator, CredentialManager, Email APIs (IMAP, Gmail), OCR (Tesseract)
