Authentication & Authorization with Clerk
Why We Use Clerk
The Authentication Problem
Building secure authentication from scratch requires:
- Password hashing (bcrypt/Argon2 with proper salts)
- Session management (secure cookies, expiration, renewal)
- Password reset flows (secure token generation, email verification)
- Account lockout (prevent brute force)
- MFA support (TOTP, SMS, authenticator apps)
- Social login (OAuth flows for Google, GitHub, etc.)
- User database sync
- Security best practices for all of the above
Time to implement securely: 2-4 weeks for experienced developers
For vibe coders using AI: High risk of security gaps
