Usage & Trade-offs
All fields support markdown. Use concise bullets and concrete situations.
When to use it
*
Integrate an Auth Module when: - Building user-facing applications with personal data. - Requiring secure API endpoints for logged-in users. - Implementing social logins or multi-factor auth. - Ensuring compliance with standards like GDPR.
Pros
*
- Centralizes security logic for easier maintenance. - Supports stateless JWT for scalable APIs. - Reduces boilerplate with libraries like Passport.js. - Handles edge cases like token refresh automatically. - Integrates with databases for user persistence.
Cons
*
- Security vulnerabilities if misconfigured (e.g., weak hashing). - Adds complexity to stateless designs with sessions. - Performance overhead from encryption/decryption. - Third-party dependencies introduce supply chain risks. - User experience friction with failed logins.
Notes
Note: Always use HTTPS and secure cookies for session auth. Implement rate limiting on login endpoints. Audit for OWASP top 10 risks regularly.
