description: Authentication security testing - auth bypass, JWT attacks, OAuth flaws, password attacks, 2FA bypass, CAPTCHA bypass, and bot detection evasion.

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`):

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

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

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
