Answer from AI
Storing JSON Web Token (JWT) in a cookie is recommended for several reasons related to security and convenience:
- HttpOnly and Secure flags: Cookies can be configured with HttpOnly (not accessible via JavaScript) and Secure (transmitted only over HTTPS) flags, reducing the risk of XSS attacks and token interception.
- Automatic sending: The browser automatically sends cookies to the server with each request to the corresponding domain, simplifying authentication.
- Lifetime management: Cookies support setting expiration times and renewal policies.
Unlike localStorage or sessionStorage, which are accessible via JavaScript and vulnerable to XSS, cookies with proper settings provide a higher level of security for storing JWT.
