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

**CredentialManager** (`tools/credential_manager.py`):
```python
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)

## Commands

```bash
/authenticating                  # Full test
/authenticating --test=2fa       # Specific area
/authenticating --report         # Generate report
```
