Most developers build a login page. Few build a system for real security. I built an auth system for Next.js. It goes beyond signup and login.

Basic systems stop at password hashing. Production systems need more.

You need:

• Secure session management.
• Refresh token handling.
• Token rotation.
• OTP verification.
• Password reset flows.
• Device-wide logout.

My system uses:

• JWT Access Tokens.
• Refresh Tokens.
• Token Rotation.
• OTP Verification.

Access tokens are short. Refresh tokens keep you logged in. This keeps your data safe.

Token rotation helps. The system kills the old token. It gives you a new one. This stops replay attacks.

I added OTP for:

• Account activation.
• Sensitive changes.
• Password recovery.

Session tracking is key. You see all active devices. You log out from all devices at once. This protects your account.

My security list:

• Password hashing.
• HTTP-only cookies.
• Token expiration.
• Rate limiting.

Auth is not a feature. It is infrastructure. Good planning makes a strong base for your app.

What auth features do you use?
