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

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