About this skill
Secure Authentication Flow Reviewer examines signup, login, verification, password reset, multi-factor authentication, session management, logout, account recovery, OAuth, and authorization handoffs. It identifies account takeover risks, weak token handling, insecure defaults, data leakage, abuse paths, and missing monitoring.
What it does
The skill maps authentication actors, credentials, tokens, trust boundaries, storage, sessions, permissions, and recovery paths; reviews validation and error behavior; identifies brute force, enumeration, replay, fixation, CSRF, and privilege risks; and produces a prioritized remediation and test plan.
What is included
- Authentication flow map
- Token and session review
- Authorization boundary review
- Recovery and verification analysis
- Abuse and account-takeover scenarios
- Security control recommendations
- Adversarial test cases
- Monitoring and incident checklist
How to use it
1. Download the secure-authentication-flow-reviewer-SKILL.md file 2. Upload it to your development or security workspace 3. Provide flow diagrams, code, endpoints, token behavior, and user roles 4. Add framework, identity provider, and deployment details 5. Use the output for engineering remediation and specialist review
Examples
Review an authentication system using email and password login, JWT access tokens, refresh tokens in cookies, password reset links, Google OAuth, and admin roles.
A structured review covering token storage, refresh rotation, cookie flags, CSRF, session revocation, password reset, OAuth state, account linking, enumeration, brute force, admin authorization, logging, tests, and remediation priorities.
