01
How to use
- Enter cookie name (e.g. session_id or auth_token) and sample value.
- Toggle security flags: HttpOnly, Secure, SameSite (Strict, Lax, or None), and Partitioned (CHIPS).
- Set optional Domain, Path, and Max-Age expiration in seconds.
- Select your target framework tab (Express.js, NestJS, Next.js Middleware, Nginx, or Apache).
- Review your live Cookie Security Rating and copy ready-to-use backend code snippets.
02
Understanding the output
The generator creates standard `Set-Cookie` HTTP headers and server-side framework configurations following OWASP Session Management security guidelines.
03
Common issues & tips
- •Setting `SameSite=None` requires the `Secure` flag to be enabled, otherwise modern browsers reject the cookie.
- •Cookies without `HttpOnly` can be accessed by client-side JavaScript (`document.cookie`), making authentication tokens vulnerable to XSS theft.
Frequently asked questions
- Why should session cookies always have HttpOnly enabled?
- HttpOnly prevents client-side JavaScript from accessing session tokens, protecting them against XSS theft.
