Auth Token Inspector

Core Principles

  1. Secure Storage: JWTs or session tokens must NOT be stored in localStorage or sessionStorage due to vulnerability to Cross-Site Scripting (XSS).
  2. HttpOnly Cookies: Deliver tokens via HttpOnly, Secure, and SameSite=Strict (or Lax) cookies to protect them from client-side JS access.
  3. Short Expiration: Ensure access tokens have short expiration times, and implement secure, rotation-enabled refresh tokens stored in cookies.

Storage Comparison

Storage ModeVulnerable to XSSVulnerable to CSRFRecommended
localStorageYes (High Risk)NoNO
sessionStorageYes (High Risk)NoNO
HttpOnly CookieNo (Secure)Yes (Mitigated via SameSite/Tokens)YES
