About Cookie Security Checker
Cookie Security Checker is used to inspect the security attributes of cookies set by a website — Secure, HttpOnly, SameSite, and expiry. It fetches the URL and parses all Set-Cookie headers, flagging cookies missing important security attributes. Session and authentication cookies should always have Secure and HttpOnly set, and SameSite=Strict or Lax to prevent CSRF attacks. Cookie Security Checker runs free in your browser at abovetool.com — no signup required.
