# Authentication

Test authentication mechanisms including login security, token handling, 2FA, CAPTCHA, and bot detection.

## Techniques

| Type | Key Vectors |
|------|-------------|
| **Auth Bypass** | Default credentials, logic flaws, response manipulation |
| **ADFS/SAML** | Golden SAML, token signing cert theft, assertion manipulation, SAML wrapping |
| **JWT** | Algorithm confusion, key injection, claim tampering, token forging |
| **OAuth** | Redirect manipulation, CSRF, token leakage, scope abuse |
| **Password** | Brute force, credential stuffing, password policy bypass |
| **2FA Bypass** | Response manipulation, direct endpoint access, code reuse, race conditions |
| **CAPTCHA Bypass** | Missing server validation, token reuse, OCR, parameter manipulation |
| **Bot Detection** | Behavioral biometrics simulation, fingerprint randomization, stealth mode |

## Tools

**PasswordGenerator** (`tools/password_generator.py`):
```python
from tools.password_generator import generate_password
password = generate_password(hint_text="8-16 chars, uppercase, numbers")
```

**CredentialManager** (`tools/credential_manager.py`):
```python
from tools.credential_manager import CredentialManager
mgr = CredentialManager()
mgr.store_credential(target="example.com", username="test", password="pass")
```

## Workflow

1. Analyze auth implementation (forms, tokens, 2FA, CAPTCHA)
2. Test bypass vectors per technique type
3. Use Playwright MCP with human-like behavior (typing 80-200ms, random pauses)
4. Capture evidence (screenshots, network logs, tokens)
5. Document findings with PoC scripts
