How do you design a secure authentication flow for a full stack app?
Answer
A secure auth flow covers login, session management, and authorization.
**Common approach:**
- Use secure sessions (httpOnly cookies) or JWT access+refresh tokens
- Add MFA for sensitive apps
- Enforce authorization on the server for every request
- Protect against XSS/CSRF (CSP, SameSite, CSRF tokens)
Also implement audit logs, rate limiting on login, and safe password storage (Argon2/bcrypt).
